Flatpak install on MX Linux

Hello again. I have 2 things to bring to the table. I had to install the flatpak of JAMI on MX because there are some issues with snaps and MX’s default Vinit. The snap of JAMI worked fine with Ubuntu 22.04, as far as I could tell. But on MX, the flatpak version recognizes the Logitech Brio 4k webcam, but does not preview, even to use the webcam for the profile pic. And, JAMI isn’t able to access files on a secondary hard drive, where I keep all my digital ‘stuff’. Are there things that I can do to remedy these issues?

the jami team doesn’t provide the flatpak version, but there is a repo for debian stable that should work
