Additional team and channel-related features and issues within Microsoft Teams for business
Dear Ayan,
I am Renzo, as an Independent Advisor and Office user, I'll help you with your question.
You should add your own AppID and Password from App Studio to your code.
There are times when you may need to create bots in Microsoft Teams that can access resources on behalf of the user, such as a mail service.
In below link you will find an article where they demonstrates how to use Azure Bot Service v4 SDK authentication, based on OAuth 2.0. This makes it easier to develop a bot that can use authentication tokens based on the user's credentials. Key in all this is the use of identity providers, as we will see later.
