Anyone who has the Amazon Chime desktop app installed can share their screen or get remote access, not just the meeting organizer. To do this, choose Screen, and then choose Share Screen to share your whole screen or Share Window to share a specific window. Desktop users see a Shared screen pop-up, and mobile users see an alert to ignore or view the shared screen.
If you're sharing your entire screen on your Windows or Mac desktop app, one or multiple attendees can request keyboard and mouse control of your desktop by choosing Share, Request Shared Control.
