Hello,
i am trying to send messages in a Teams Channel.
I configuerd like descriped in the docomention, and authentication in the connection settings works. But if a make a task for sending channel messages it fails to retriev teams or channels, and brings an Error Message with an "Unknown Errror".
If i type in the team and channel myself, the task fails also with an unknown error. Maybe there are premissions missing?
I have granted the following premissions in Azure AD.
