Error on autotype with Flatpak app on Ubuntu - ModuleNotFoundError: No module named 'Xlib'

[MurzNN]

When I'm trying to make autotype on the goldwaren installed from Flatpak, I get an error in the console:

/app/bin/src/gui/quickaccess.py:159: DeprecationWarning: Adw.ActionRow.set_icon_name is deprecated
  action_row.set_icon_name("dialog-password")
/app/bin/src/gui/quickaccess.py:113: DeprecationWarning: Gtk.Widget.hide is deprecated
  self.window.hide()
Exception in thread Thread-2 (perform_autotype):

    from Xlib.display import Display
ModuleNotFoundError: No module named 'Xlib'

Installing the xlib library locally like this:

$ sudo apt install python3-xlib

doesn't help, seems because Python checks it in the Flatpak namespace.
