I've seen it inferred here, but not confirmed. Can one transit from the non-French side of GVA to the French side via the AF/KLM lounge?

I am flying GVA-CDG on AF, so I presume this flight leaves from the French side. However, I'd like to visit the Swiss lounge before departure. (It does appear that AF/KLM lounge is open to me as a Priority Pass member during the hours of my flight.)
