Core22, Python and Gtk3 with gnome extension

I made a test snap for core22, Python, Gtk3 and the gnome extension and it’s working:

but I get this when I start the snap: Gtk-Message: 18:59:25.540: Not loading module “atk-bridge”: The functionality is provided by GTK natively. Please try to not load it.

what do I need to do?

Did you subsequently also get this?

GTK+ module /snap/hellognome/x2/gnome-platform/usr/lib/gtk-2.0/modules/ cannot be loaded. GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported.

Yes, but only when using Xorg. Also got: ** (hellognome:153704): WARNING **: 16:06:48.413: atk-bridge: get_device_events_reply: unknown signature
