We are continuing to work on this feature. As with Windows notifications, we are also doing work to give users the choice between Teams notifications & Mac notifications.
We will update you as work progresses.

Changing Display Names for guests in Azure portal will successfully update them across all the various admin portals for Teams and Office 365, but doesn't update in the Teams app even after quitting the app, logging out and in again, etc.
If this is only changed for Admins to see, then I don't really see the point of being able to update guest user info at all.
