[SOLVED]Black Mesa Legacy (free legal non Steam version) + Source SDK

Hi, i’m running this game with Source SDK but is needed to add “-game BMS” as startup option for Source SDK in steam client. My question is why “-game BMS” option added as a parameter for application 218 witch is Source SDK is not working. Am I missing something? it seems the position “Arguments” is only a parameter for Steam not for App (as description says). So is possible to add parameters to App?. Thanks for any advice.

SOLUTION-obsolete:
running Source SDK without Arguments but in that way as application:
218//-game BMS
After the game is started is needed to accept running SDK with additional parameters.

SOLUTION for lutris 0.4.7.1:
As argument for steeam application 218 (Source SDK 2007)
-game BMS
and put downloaded game into …Source SDK Base 2017/BMS

Sadly after restarting Lutris Black mesa Legacy is marked as uninstalled. Is this because of some kind of valitation data given as steam application:
218//-game BMS instead of only 218?
