There is a code in https://code.mendhak.com/Airflow-MS-Teams-Operator/ source code https://github.com/mendhak/Airflow-MS-Teams-Operator that can be used as ground work

I will try to find time to work on this but if someone has time to work on it before it's OK

Policy for adding new provider is explained at https://github.com/apache/airflow/blob/main/PROVIDERS.rst

I'm going to close this issue as the process of adding a provider require investment and commitments from the requester thus it's unlikely that someone will just pick up this request and implement it so no reason to keep this issue open.
