Exports menu on connection at object_path.
The implemented D-Bus API should be considered private.
It is subject to change in the future.
An object path can only have one menu model exported on it. If this
constraint is violated, the export will fail and 0 will be
returned (with error set accordingly).
You can unexport the menu model using
g_dbus_connection_unexport_menu_model() with the return value of
this function.
Since 2.32
