public ActionGroup action_group { set; }
Warning: action_group is deprecated since 2.32.
The group of actions that the application exports.
Use the [iface@Gio.ActionMap] interface instead. Never ever mix use of this API with use of `GActionMap` on the same
application or things will go very badly wrong.
