MS 365 Management Pack in SCOM

I'm in the process of configuring the Microsoft 365 watcher node in SCOM. I've created a private team and a private channel, but I'm encountering the following error:

I've added a subscription based on certificate authentication.

System.Exception: ERROR: Unable to remove document from Teams (Teams: 'SyntheticTranscation'; Channel: 'M365Channel').

What should I do?
