DeadSimpleScreenShare screen sharing not working when initiated from Rocket.Chat

Description

We are using DeadSimpleScreenShare integration as described here: https://rocket.chat/docs/administrator-guides/integrations/deadsimplescreensharing/

However, when the meeting is initiated from roketchat(Private rooms, DM and channels), and the screen is shared, other users who joined the meeting can not see the shared screen.

BUT when the meeting is initiated from the Web Browser extension(tested with Chrome and Fireox), users can see shared screen.
