@dpreacher@mstdn.io got it, I saw you had open suse in your profile so I thought I'd try linking to that forum hoping it would be closer to the direction. I am unfortunately not seeing how to do this in it's cli. For Ubuntu this is recommended:
'''The file associations for each user are stored in:
~/.local/share/applications/mimeapps.list

In Ubuntu this file is almost empty. Let’s import informations from
/usr/share/applications/defaults.list
"""

But I'm unsure if this will work in my your OS.

I'll keep an eye out though.
