In my setup $DISPLAY=:1, but obviously the exact value depends on other circumstances (i.e. if there's already an open session belonging to another user it'd be :2, :3, ...). I'm not sure how X vs. Wayland plays out here, but I'm still using Gnome on X, so that should hopefully not be an issue here.
