Thanks for the replies. The new wiki documentation is much clearer, thank you!
Sadly I still seem to get something wrong, neither the flatpak nor the source built one actually show the pack if inserted into their respective paths. The pack itself should be valid, as it works when adding it to a repo, and telling the addon manager to check that repo for addons.
Here is my structure on the source built one as an example:

EDIT:
Adding the packs to the "Mod" directory will make 'em show up as if installed through the addon manager.
Known good pack linked manually into Flatpak location:
