Steam

Launches games from your Steam library via the steam:// URL scheme. Both official Steam games and non-Steam shortcuts added to your library are detected.

Games are indexed from:

• ~/.steam/steam/steamapps/
• ~/.local/share/Steam/

To manually launch a Steam game, write steam://<app_id> to a token. For example: steam://1145360 for Hades.
