Creates a #GtkPopover and populates it according to
@model. The popover is pointed to the @relative_to widget.
The created buttons are connected to actions found in the
#GtkApplicationWindow to which the popover belongs - typically
by means of being attached to a widget that is contained within
the #GtkApplicationWindows widget hierarchy.
Actions can also be added using gtk_widget_insert_action_group()
on the menus attach widget or on any of its parent widgets.
