Thanks everyone for the quick resolution, the new script works.
A few remarks:
Why is global write-out the default?
Global write-out ignores desktop files in .local/share/applications and requires admin privileges. On a multi-user system, why would everyone want the exact same menu? Why not set user write-out as the default to allow user customisation of the users own menu.
On a single user system user write-out is always prefered.
In my opinion, based on the above user write-out should be the default.
