Currently, I'm developing on  visionOS. WorldTracking worked, but still don't know how to persist WorldAnchor. That is what I want: User A: deploy 3D content in WorldTracking and get WorldAnchors, and saved the Anchors. User B: come to the same place, and load saved Anchors by A, and then User B can view what A have deployed.

In the Space format, I want to scan the QRCode and then load relative 3D content.

such as a human model, use code to let him walk to a certain position?
