Look at 
https://gitlab.gnome.org/GNOME/gtkmm-documentation/-/blob/gtkmm-3-24/examples/book/menus_and_toolbars/examplewindow.cc

I think that's what you can do. Create a Gio::SimpleActionGroup. Add 
your actions to it. Insert it in your widget with Gtk::Widget's 
insert_action_group() method. In the call to insert_action_group() you 
choose what prefix to use in the ui file.
