I have two agents created in Copilot Studio. I would like to call agent B from agent A as a skill. I have created a manifest.json file and have it publicly available. In the manifest.json file , in the endpoints I have used the endpoint supplied in Copilot studio channels for Agent B from mobile app for "endpointUrl" and have used the agent B id for "msAppId". When I attempt to validate the skill I receive the error "There's a mismatch in your skill endpoints." Do I need to register Agent B as an app in AD Entra and use those endpoints and id in the manifest.json ? thanks

manifest.jsonfile. Here are the steps to do this:- Register Agent B in Microsoft Entra:
- Sign in to the Microsoft Entra admin center as at least an Application Developer.
- Navigate to Identity > Applications > App registrations.
- Select New registration and provide a name for your app.
- Choose the appropriate Supported account types.
- Click Register to complete the registration.
- Configure the App Registration:
- After registration, go to the app's Overview page and note down the Application (client) ID. This will be used as the
msAppIdin yourmanifest.json. - Under Manage, select Certificates & secrets to create a new client secret if needed.
- Under API permissions, ensure the necessary permissions are granted for your app.
- After registration, go to the app's Overview page and note down the Application (client) ID. This will be used as the
