Screen sharing in a meeting

How can share may screen or my browser in a meeting? In Saxion there is this element, but I can’t found how to add to may world and how to use it.

in our project, we use this one instead. …
GitHub - muaz-khan/RTCMultiConnection: RTCMultiConnection is a WebRTC JavaScript library for peer-to-peer applications (screen sharing, audio/video conferencing, file sharing, media streaming etc.).

Very interesting!!! Thanks
