I think something that adds language about where to look when this happens would be helpful.

raise KeyError("get_token() response is missing access_token key which indicates an error communicating with MS Teams. Check the app_id and app_secret.")

Good point

Updated to:
"get_token() response is missing access_token key, which indicates an error communicating with MS Teams. Check the app_id and app_secret."

@MeganerdDev I think this makes sense, but we do need to get the tests passing.

Thanks for adding this debugging, this will be very helpful in troubleshooting MS Teams issues.
