I am a member of a lot of Teams and Outlook groups, and when I go into the PowerBI Workspace area, every single one of them has its own Workspace, even for groups and teams where it makes no sense. There is an option "Leave Workspace" which I chose to try to simplify the PowerBI space, but that actually threw me out of the associated Teams and Groups. It should be possible to leave or hide a PowerBI Workspace without leaving the associated structure. Is this a bug?
This is how it appeared in the Team space (note, there is nothing to show for Outlook groups, they just disappeared from my Outlook application)
