Add an icon or strong visual indicator that screen share is working so that people are confident they can start talking about the shared content. Additional feature request: Use a double checkmark, where the single check shows when the screen share is started, and the 2nd checkmark shows up when the system has confirmed the screen share is working for everyone else!

Just as we can raise our thumbs up as a reaction in a video call, it would be great to have a reaction to confirm that the screensharing is on, and that yes, we can see the person's screen. I feel like we always loose so much time asking "can everyone see my screen now? yes, no?". It would be great to have this tool, so that we wouldn't waste time asking the question and waiting for the answer.
