How I can see the TRPs of players from the opposite faction?

I might be mistaken, but I vaguely remember being able to see the TRPs of players on the opposing faction some years ago with the CrossRP addon. I've just returned to WoW, but the addon doesn't seem to work even after applying the .toc file fix that someone mentioned in the comments. Is there anyway to see TRPs cross-faction?

edit: thanks for the responses everyone, a little disappointing that it's broken but I'm glad to hear it at least works in parties!
