To enable screen sharing, click the Screen button during the video conference.
Select which screen or browser tab do you want to share > click Share.
If there are more than two people participating in the video conference, you can pin the colleague's or guest's window in the Speaker mode.
The special panel will appear when the screen sharing is enabled. To disable showing your screen, click the Stop button on the panel or the Screen button.
There is also a button to stop screen sharing during the call.
The Bitrix24 app has its own panel with additional buttons to change the source of screen sharing without completing the previous one: back to call, switch to another window and stop.
