A couple of days later I managed to get this working, although the the
though question was not whether it was possible, but how to actually
do it.

I ended up using flatpak-builder, following the examples from the wiki
on the github page.

I assume that the requirement comes from CEF ( Chromium Embedded
Framework ) which is used as a basis for the editor. The editor itself
does not require direct access to devices.
