Does anyone know how to import the real time 3d face models (we've seen it in new apple FaceTime previews) to your programs as a dev? p.s... anyone want to collab?

Hello, is anyone aware if or how it is possible to test apps that use SharePlay for vision os for each devices perspective that is participating? I tried to make two simulator sessions signed into two different IDs invite each other to a session but that is not working. Im trying to see the "Happy Beam" demo in action between two devices. Is there something I'm missing? Thanks
