Flatpak permissions for JACK

Does anyone remember how to enable flatpak applications to access jack? I DON’T have pipewire installed (I spent a good 8 hours trying to wrap my head around how to make it do the things that I’m used to from Jack, and gave up on it). But nothing that’s flatpak can seem to access the Jack server. According to flatseal obs for example has device=all & xdg-run/pipewire-0. I tried giving it access to /dev/shm and that didn’t seem to help.

Can I force flatpak to stop trying to use pipewire?

Thanks!
