It seems that "steam://" doesnt work. But when I enter this URL in the Runner (ALT+F2) the game starts fine.

I needed to add the mime-type to $HOME/.local/share/applications/steam.desktop. There is another steam.desktop with the correct setting in /usr/share/applications/steam.desktop but that's not the right one I guess... I just used the manjaro default installation/version and never changed anything. So everyone need to edit these files manually to use GameHub? Strange somehow :/

EDIT:

Also needed >>

update-mime-database $HOME/.local/share/mime
update-desktop-database $HOME/.local/share/applications
