Plutonium

Hi,
I'm trying to set up Plutonium with Playnite as a one click launch, which of course would necessitate using the command line to select the game. Unfortunately, going directly through the bootstrapper doesn't work, as I'm unable to provide it with the authentication token (other than that, it works perfectly - but I'd need to get a token through the launcher and then add that to the arguments each time, which defeats the purpose). Is there any way to generate the token through scripts (which Playnite supports - could even be made into an extension), or to provide a command line argument to the launcher so it launches the correct game immediately?
