Allow posting messages to Teams with Azure App rather than delegated permissions
Currently you cannot post messages to Teams with application permissions, only delegated permissions are supported.
This work is on the backlog and currently isn’t scheduled. The feature will be updated here once dev work is started. -EY

This is something that would really make a difference to our ability to build a secure collaboration integration with our web app. Please uplift the priority of this item.
As per other comment - can you expand this to cover other channel message functions - Get/List Channel messages - Get/List Channel replies.
This may not be what the OP intended, but if development of this is blocked by concern over giving wide permissions (to all messages) to an application then I think it would still be appropriate to allow posting (and potentially other message level functions) to a channel that the application had created.
