Provide webhooks for Microsoft Teams messages.
We are integrating Microsoft Teams threaded chat into our product offering. Our users will interact with the channel-based chat using both the Microsoft Teams application and from within our application. To avoid polling, we would like to be able to subscribe to Microsoft Teams related events. Of interest are events related to new channel messages. We found similar subscriptions for files and email, but nothing related to Microsoft Teams.
