Block attachements of a message as an app

[unglaublicherdude]

Is your feature request related to a problem? Please describe the problem.

We are trying to implement an antivirus for teams and have already found the chatMessagePolicyViolation. When using this, a message can replaced with an alert-message and the original content is gone. But setting a policy violation will not change attachements. And when we basically replace the file on onedrive, the preview in the message will still persist which is a bit confusing for users.

Describe the solution you'd like.

I would like a way to also remove attachements from a message when a chatMessagePolicyViolation is set.

Additional context?
