When the app is properly launched, D-Bus activation will be followed by a call to org.freedesktop.Application.Activate() to open the window. But it's also possible for D-Bus activation to happen in other circumstances, for example during gdbus command line completion. We don't want to pop up a window then, so pass the --gapplication-service flag to properly separate D-Bus activation from activating the app. Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2076>
