How to add gamepath ? - World War Z

so recently, i got this game from my friend  and i want to use plitch in-game but unfortunately, no option to add game path. I remember when PLITCH's name was MegaDev and in MegaDev itself, i can add the gamepath. Any solution ?

Are you playing via epic or msstore?

If you play via msstore you have to launch the game manually via msstore or the xbox app (whatever you are using)
If you play via epic you have to go to the installation folder of the game and select this exe "wwzRetailEgs.exe"
You can also start the game manually via epic. The play-button has nothing to do with the cheats... it just starts the game.
