Show Selfview while in a Meeting and started

Show Selfview while in a Meeting and started Sharing and the only participant in the Meeting

We have many users who schedule and join a meeting, start already screensharing and also sharing their video.

They are complaining that the Selfview is shown

1) As long as they are not sharing their screen
2) Again as soon as a second attendee is joing the meeting

For a good meeting experience (to see the selfview before an attendee is joining) the Selfview should be always visible.
