Passing parameters to Flatpak app

Hi Everyone,

On non-flatpak version of Signal I am able to pass “–use-tray-icon” by editing the shortcut so the app keeps running in the background.

I have tried to do this with flatpak version of Signal, but I can’t seem to find where to add the launch paramter. The shortcut looks like this
“/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=signal --file-forwarding org.signal.Signal @@u %U @@”

Can anybody advise?

Same thing brought me here. In case anyone else still has this problem, it’s actually very easy:

/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=signal --file-forwarding org.signal.Signal --use-tray-icon @@u %U @@

(as of today, the flatpak build misses the icon file, so Signal will be the “no icon symbol” in the tray)
