But that is why I for work stuff use Chromium and I didn't really have issues with it. The things in this list:
System notifications - works with Chromium
System tray integration (badge support varies by desktop environment) - I don't have a system tray on Hyprland with waybar
Custom backgrounds & themes - ok, I never needed it but that is probably the only thing which is not working in Chromium
Screen sharing support - Always worked, as long as you allow it
Multiple account profiles - I'm doing that with different Chromium profiles, but yeah it kind of would be nice if it was possible in one window, so that seems also cool
But for those two features it seems it's more hassle to deal with a unofficial version.
