Ummm. .. not always the case that the client is at fault. For example the layer shell protocols of Wayland allows you to create desktop components like popup menus etc. Now the tricky part is established desktop environments like GNOME uses the xdg_surface, hence GTK only has binding or focuses explicitly on that. This has given others who wants to implement a layer shell like this gtk-layer-shell library has to do some hacking as workaround. As you see currently only tested to work with gtk3 2.24 26.while many rolling releases are already shifting gtk3 2.24.30. Some window managers or rather say status bar like waybar ( the most popular status bar project ) uses this library. And this creates problem for those wants to use any status bar that depends on tk layer shell library and are on recent updates on gtk. Gtk only sees xdg_surface, is not in a mood to support other libraries.
i don't know what DE you use, but on Sway KDE and GNOME there is xdg-desktop-portal that allows screen sharing (no sharing of one specific app for the moment). It worked for me on discord and jitsi meet. Now we have to wait until all software use it
