Ok, so the native needs to be added to steamworks (and the person who made it is no longer active on these forums, yay).
SetGameData(
const char *pchGameData).
I still don't understand what string value to put in here. SetGameData("grp:123456i,grp:123457i,grp:1234 58i,key:myse archkey2151") ?
Btw. they don't need luck. Workshop mod will take care of everything.
