Re: where does the this file belong on a debian 12uptodateamd64system?

There isn't any executable: that isn't how flatpak works. There's no
need for you to deal directly with anything under /var/lib/flatpak. To
run prusa-slicer type "flatpak run com.prusa3d.PrusaSlicer".  I suggest
making a script named prusa-slicer that executes that command and
putting it in /usr/local/bin.

This is all documented on the prusa site and the flathub prusa page.

To remove a flathub package type "sudo flathub uninstall <packagename>".
