Unfortunately the issue persists even if I give Heroic access to the all user files (filesystem=home), but maybe the issue is more an issue of Steam rather than of Heroic, since from Heroic I’m able to launch games and even add them to Steam (they actually appear on Steam Library, and manually launching from a terminal the command Heroic automatically added to steam games are launched properly).

I tried to give Steam flatpak full access to user’s files as well, but after having done that I got an error when launching steam pointing me to this doc page so I think some additional steps would be needed for that change (?)

Because sometimes I have the laptop connected to the TV using Steam’s Big Picture mode with a controller and it would be nice to launch also my Heroic games from there without having to go back to the desktop

Anyone willing to summarize those mistakes here, for those who can’t watch the video rn?
