So we are using gamesparks in UE4 and the things we have tested work fine,
But we are trying to make the following work with gamesparks
User Login with launcher -> Check for updates ..etc..etc -> Start Game -> Authenticate User Using Launcher (sessionid?, jwt token?)
We have gamesparks login working fine in game but we want to make the login work using our launcher, this way we can make sure game is up to date, advertise new upcoming events, upcoming updates, patch notes... etc.
So the real question is how can we share or send the login session to UE4, we can make command parameters in c++ Game.exe -GSSession <sessionid>
Sorry for the spelling English is not my first language.
