See the Audience View
The Audience View pane displays a thumbnail view of what attendees see when you share your screen. This helps you confirm that attendees are only seeing what you want them to see (and remind you to turn on screen sharing if you've forgotten).
In addition, a green bar at the top of the pane displays a percentage of how many attendees have the Viewer at the forefront of their screen (versus those who have it in the background and are not attentive). To see which specific users are attentive and which are not, open the Attendees pane and look for the Non-Attentive icon .

1. Tap the Screen Sharing icon .
2. Use the Audience View toggle to show or hide the pane. You can also tap the icon on the pane to close it at any time.
