Open this page in your headset's own web browser (on a Meta Quest, the Browser app) and press VR there to stand among the worlds.
This browser can't show VR. Headsets that support WebXR, the web's VR standard, work.
3D cities and street photos need keys of your own. They stay in this browser only and go nowhere but to Google or Mapillary. Limit a key to this site and a daily quota in the service's settings.
