Screen sharing ungoogled-chromium

[phodina]

Hi,

I'm attempting to share my screen in the chromium browser (100.0.4896.127-1).

I've enabled the #enable-webrtc-pipewire-capturer flag and I also have 
xdg-desktop-portal install on my Guix System.

However, when I click in Teams on share the whole desktop, window or just a 
chromium tab the browser crashes and shows in the window the following error.

Aw Snap, something went wrong!

Error code: 4

In the console I see several of these errors to appear:

[29296:29312:0428/074526.629746:ERROR:bus.cc(397)] Failed to connect to the 
bus: Could not parse server address: Unknown address type (examples of valid 
types are "tcp" and on UNIX "unix")

Does somebody use the screen sharing feature?

I'm currently running on X11 (i3-gaps).
