Hello,
I have installed Steam via flatpak, and it autostarts independently of the setting set in app.
It doesn’t appear in the Autostart GUI in the settings, and I can’t find any related .desktop file in the autostart folders ~/.config/autostart/, /etc/xdg/autostart/, /usr/share/applications/ or ~/.var/app/com.valvesoftware.Steam/config/
Theese are the spots where steam appears when running journalctl -b 0:

Is there a way to disable the autostart?
I installed Steam via flatpak because when installing it natively proton games wouldn’t run.
