rf2 Leaderboard Car Class Question

Hi Wotever, I hope all is well.

I am trying to change the car class background color of a Simhub leaderboard so I can differentiate  between classes.  In javascript I can use the highlight setting to do that.  I have not been able to determine which variable I need to use for that in the leaderboard as I can only see in the available properties the DataCorePlugin.GameData.CarClass variable, but that is only for the user of the game.  Need the variable to use in the leaderboard itself, something like Leaderboard.Opponent.CarClass, I assume. Does that option exist?  I see Gary Swallow manages to do it somehow in his plugin to show the class icon, but it does not show which variable is being used to compare.

Thanks in advance for your help.  Cheers.
