As far as I'm aware Projectivy Launcher gets a lot of permissions it should not have, and it's closed source.. Feels like trading one privacy invasion for another.
Generally it seems like good READMEs assume you have a compatible OS ready to go, but will give you a summary of all commands to get a working setup from there.
Looking at the flatpak manifest it has `share=ipc` but no directories shared.. I'm not sure on flatpaks defaults for what it would actually have access to on the host.
