Prefect Version

2.x

Describe the current behavior

Only SLACK notifications and email are available through UI (docs).

Describe the proposed behavior

Like I requested for Prefect v1.0 back then (https://github.com/PrefectHQ/prefect/issues/4129), it would be nice to create notifications for MS Teams for global alerts at the UI. Like SLACK this feature should be implemented in Orion server so its available on-prem as well.

Example Use

End users who uses MS Teams in their tool stack could be alerted when flows are failing / crashing.
