Pathfinder Playtest Flip-Mat Multi-Pack - sorry have a stupid question. Where is it please? :)

I am trying this add-on. I added it to a new game and I went to Journal.  I see "Thank you, Game Settings, and Credits"  I went to the Art Library and typed "flip-mat" and "mat" for the searches and got no matches.  I did find roadside ambush buried under free assets but that was it.  Where is it and how does one add the maps?  I'm sure it's something simple... I've attached a couple screens of where I looked...

If you purchased it, did you use the add-on menu on your game page to add it into your game?

Roll20 had a link outside of the game to add the content.  I did that and it says: ”The add on Pathfinder...has been successfully added to game.” I launch it and I do not see it.  Unless it is under a different name maybe? Nothing with that name under add-ons when I launch the game except for: Pat S. said: If you purchased it, did you use the add-on menu on your game page to add it into your game?

Check your map pages or your card decks. Sometimes they are added that way and not to your art library. --Edit-- I just created a blank test game and added it. They show up in your map pages.
