Floating Shared Screen controls not showing after last update

When sharing a screen on a webinar there was always a floating screen with meetings controls (start/stop audio, start/stop camera, etc...) but since the last update, the controls now stays on a screen with the shared content, how do i enable the floating controls again? i cant keep opening the webinar window to see of there is any Q&A or to perform other actions, and the controls i could move around so it is kind of necessary.

And also, how do i make the chat window to auto-scroll? after the update it keeps appearing how many new messages there is and i have to keep scrolling down myself, but i want it to act like it was before, when it just scrolled down automatically.
