I can access the new lenses in the app. Haven’t tried using them since I’m still at home, impatiently waiting for to get on a plane to DLR in a couple weeks.
The info I’ve read indicates some of the lenses are themed and location specific (I.e. Grogu lens only in Galaxy’s Edge), but others are not.
You have to update your app for the new lenses, and then there should be a tour of the new features which pops up.
