Prerequisites

Microsoft Teams is installed and you have an account (not a guest account)
NodeJS
dev tunnel or ngrok latest version or equivalent tunnelling solution
M365 developer account or access to a Teams account with the appropriate permissions to install an app.
Teams Toolkit for VS Code or TeamsFx CLI

Run the app (Using Teams Toolkit for Visual Studio Code)

The simplest way to run this sample in Teams is to use Teams Toolkit for Visual Studio Code.

Ensure you have downloaded and installed Visual Studio Code
Install the Teams Toolkit extension
Select File > Open Folder in VS Code and choose this samples directory from the repo
Using the extension, sign in with your Microsoft 365 account where you have permissions to upload custom apps
Select Debug > Start Debugging or F5 to run the app in a Teams web client.
In the browser that launches, select the Add button to install the app to Teams.

Setup

1. Setup for App Registration

Register a new application in the Microsoft Entra ID – App Registrations portal.
Select New Registration and on the register an application page, set following values:
- Set name to your app name.
- Choose the supported account types (any account type will work)
- Leave Redirect URI empty.
- Choose Register.
On the overview page, copy and save the Application (client) ID, Directory (tenant) ID. You’ll need those later when updating your Teams application manifest and in the appsettings.json.
Under Manage, select Expose an API.
Select the Set link to generate the Application ID URI in the form of api://{AppID}. Insert your fully qualified domain name (with a forward slash "/" appended to the end) between the double forward slashes and the GUID. The entire ID should have the form of: api://fully-qualified-domain-name/{AppID}
- ex: api://%ngrokDomain%.ngrok-free.app/{{00000000-0000-0000-0000-000000000000}}.
Select the Add a scope button. In the panel that opens, enter access_as_user as the Scope name.
Set Who can consent? to Admins and users
Fill in the fields for configuring the admin and user consent prompts with values that are appropriate for the access_as_user scope:
- Admin consent title: Teams can access the user’s profile.
- Admin consent description: Allows Teams to call the app’s web APIs as the current user.
- User consent title: Teams can access the user profile and make requests on the user's behalf.
- User consent description: Enable Teams to call this app’s APIs with the same rights as the user.
Ensure that State is set to Enabled
Select Add scope
- The domain part of the Scope name displayed just below the text field should automatically match the Application ID URI set in the previous step, with /access_as_user appended to the end:
  - `api://[ngrokDomain].ngrok-free.app/[App-id]/access_as_user.
In the Authorized client applications section, identify the applications that you want to authorize for your app’s web application. Each of the following IDs needs to be entered:
- 1fec8e78-bce4-4aaf-ab1b-5451cc387264 (Teams mobile/desktop application)
- 5e3ce6c0-2b1f-4285-8d4b-75ee78787346 (Teams web application)
Navigate to API Permissions, and make sure to add the follow permissions:

Select Add a permission
Select Microsoft Graph -> Delegated permissions.
- Chat.Read
- Chat.ReadWrite
- ChatMessage.Send
Click on Add permissions. Please make sure to grant the admin consent for the required permissions.

Navigate to Authentication If an app hasn't been granted IT admin consent, users will have to provide consent the first time they use an app.

Set a redirect URI:
- Select Add a platform.
- Select Single Page Application.
- Enter the redirect URI for the app in the following format: https://{Base_Url_Domain}/auth-end. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your {Base_Url_Domain} will be1234.ngrok-free.app and if you are using dev tunnels then your domain will be 12345.devtunnels.ms.

Navigate to the Certificates & secrets. In the Client secrets section, click on "+ New client secret". Add a description(Name of the secret) for the secret and select “Never” for Expires. Click "Add". Once the client secret is created, copy its value, it need to be placed in the env file.

2. Setup NGROK

Run ngrok - point to port 3978
```
ngrok http 3978 --host-header="localhost:3978"
```
Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:
```
devtunnel host -p 3978 --allow-anonymous
```

3. Setup for code

1. Clone the repository

git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

In the folder where repository is cloned navigate to samples/graph-pinned-messages/nodejs
Update the .env configuration with the MicrosoftAppId, MicrosoftAppPassword and MicrosoftAppTenantId with values generated in step 1 while doing App Registration.

Note: Navigate to samples\graph-pinned-messages\nodejs\ClientApp\src\components\dashboard.jsx - On line 88, replace {{ChatId}}

3.1. Install node modules and run server

Inside node js folder (samples/graph-pinned-messages/nodejs), open your local terminal and run the below command to install node modules. You can do the same in Visual studio code terminal by opening the project in Visual studio code

npm install

npm start

If you face any dependency error while installing node modules, try using below command

npm install --legacy-peer-deps

3.2. Install node modules and run client

Navigate to samples/graph-pinned-messages/nodejs/ClientApp folder, Open your local terminal and run the below command to install node modules. You can do the same in Visual studio code terminal by opening the project in Visual studio code

cd client
npm install

npm start

If you face any dependency error while installing node modules, try using below command

npm install --legacy-peer-deps

4. Setup Manifest for Teams

This step is specific to Teams.
- Edit the manifest.json contained in the appManifest folder to replace your Microsoft App Id (that was created when you registered your app earlier) everywhere you see the place holder string <<YOUR-MICROSOFT-APP-ID>> (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
- Edit the manifest.json for configurationUrl inside configurableTabs . Replace {{BASE-URL-DOMAIN}} with your app's base Url domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your base url domain will be 1234.ngrok-free.app.
- Edit the manifest.json for validDomains with base Url domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your domain-name will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.
- Zip up the contents of the appManifest folder to create a manifest.zip (Make sure that zip file does not contains any subfolder otherwise you will get error while uploading your .zip package)
- Upload the manifest.zip to Teams (In Teams Apps/Manage your apps click "Upload an app". Browse to and Open the .zip file. At the next dialog, click the Add button.)
- Note Add the app to groupChat scope.
