Window icons are set using X11 properties, which means there is no
corresponding concept under Wayland (and other windowing systems).

GNOME Shell uses the desktop file for retrieving metadata like icon,
names, and actions; you need to provide a desktop file with the same
name as your application's binary, or your GtkApplication application
id, and put it under /usr/share/applications or
$HOME/.local/share/applications. The icon specified in the desktop
file is going to be the one used by the shell.
