How to programmatically add an app in a Teams meeting?

Question

I want to programmatically add an app to all my current and future teams meetings. when we start a meeting, I noticed that a meeting chat appears for that meeting in Teams. So, I thought maybe a meeting chat is automatically created when we create a Teams meeting. However, I noticed that when I call the https://graph.microsoft.com/v1.0/me/chats api endpoint, it does not return any chat object for any new Teams meeting that I create which is yet to have any chat content.

In such case, I wanted to ask:
1)Does a meeting chat get created automatically when we create a Teams meeting? If so, how do I access it since https://graph.microsoft.com/v1.0/me/chats did not give me back chat object for the respective meeting?

2)If a meeting chat is not automatically created for a new Teams meeting that we create, how can we add our desired app to our Teams meeting programmatically such that user does not have to go on to manually add the desired app to meetings everytime?

Answer 1

Currently there is no such feature available. We do not have API to add the app to all meetings at once.

Thanks,
