Screen sharing


You can share your PC screen with other participants.

You can share the screen during voice and video calls. On the mobile app, you can only view but cannot share the screen.

For those using macOS 10.15 or later versions, you must check LINE WORKS in ‘System setting > Security & Privacy > Privacy > Screen Recording’ to use screen sharing.
