Flatpak does not auto-start minimized

**Describe the bug**
I want copyq to start minimized in system tray.

**To Reproduce**
I found an older bug about this that said to:
1. delete ~/.config/autostart/copyq.desktop
2. run "copyq config autostart true"

I deleted the desktop file and then ran
flatpak run --command="bash" com.github.hluk.copyq
Inside I ran
/app/bin/copyq config autostart true

It said "true", but now it doesnt start at all anymore after a reboot.

**Expected behavior**
Copyq started in maximized mode before, I just want it to start minimized
