Automatically launching on startup, Linux Flatpak

[s20]

Heya! I'm using the Linux Flatpak, and it seems to be automatically launching on startup, or tryng to at least (I get crash reports about it). I went into the app to try to disable it, and the setting doesn't seem to be there anymore. I tried in the DE's startup apps (on Gnome 44, using Gnome Tweaks), but it's not listed there.

My only guess is that Zoom added a dbus/systemd message, and I can't seem to find it. Any help is appreciated.
