script execution behavior may be different in gaming mode

[miki223]

somebody wanted to mod assassin's creed which required running a launcher those of us helping OP write a simple script to run the launcher using prootontricks-launch the script works as expected when run from Steam in desktop mode but not gaming this is the script

#!/bin/bash
flatpak run --command=protontricks-launch com.github.Matoking.protontricks --appid 15100 "/home/deck/.local/share/Steam/steamapps/common/Assassins Creed/uMod/Assassins Creed Remastered Launcher.exe"

my guess was prootontricks was using portals to get the file portals don't work in gaming mode but it may not be
