Small Gnome Shell Extension to enable Zoom Screensharing under Wayland.
Since the Zoom client does not natively support Wayland, Wayland's "safe mode" must be disabled to enable screen sharing.
Download zip and copy the folder zoomwayland@polyte.de into .local/share/gnome-shell/extensions/. Logout and Login, the use Gnome Tweak Tool or https://extensions.gnome.org/local/ to enable it.
After installation you'll find a Icon in the Gnome Panel. Activate the Switch to enable Zoom Screensharing. A Message will appear to notice you, that "the System is in an unsecure mode". After Screenshare you can disable the Switch again.
