Jitsi screensharing chrome vs. rocketchat

(Windows 10)
When I start to share my Screen in Jitsi session in chrome I can choose from 2 Screens.
When I start the same from Rocketchat 2.17.7 I see just one screen and my mouse cursor appears only when the cursor is on the screen which is not shared.

My screen setting:
Windows main screen - left - 1920 x 1080
Shared screen - right - 2560 x 1440

Is this not an implementation issue on Rocket.Chat side?

How should I know? I see just Jitsi logo and that it doesn’t work as should.

Maybe here?
