"Start app on login" fails

[houzefa-abba]

Hi thanks a lot for this packaging, very helpful :)

I'm using it on Linux Mint, here the "Start app on login" setting does not work: it writes an autostart script with the command /app/main/mattermost-desktop --hidden which of course makes no sense from the pov of my system.

I ended up disabling the setting and adding my own autostart entry which calls the same command as the existing menu entry: /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=mattermost-flatpak --file-forwarding com.mattermost.Desktop --enable-features=WebRTCPipeWireCapturer

Would be nice if this autostart command could be adjusted accordingly when added by a flatpak'd app.
