Greetings,

If you're using Steam and installed it as a flatpak you may noticed that it doesn't make any installed game icons to your Desktop.

Here's how you do it:

1. Go to ~/.var/app/com.valvesoftware.Steam/Desktop and drag the icon(S) To your Desktop.
2. Open the icon with the text editor app.
3. Change Steam steam://rungameid/XXXXXXX to xdg-open steam://rungameid/XXXXXX

Enjoy! ^_^
