spatial-backdrop feature available yet?

In WWDC25 session What’s new for the spatial web, the presenter showed creating an immersive environment for a web page by adding to the page's HEAD section

<link rel="spatial-backdrop" href="office.usdz" environmentmap="lighting.hdr">

My first attempt failed, and I am trying to track down why.

Is this feature available in the latest visionOS 26 beta?

I haven't seen anyone talk about their use of the feature yet.

Then, look for the option in the menu to the left of the URL

If someone runs across this same problem, it does work in the headset in the visionOS 26 beta. The error was me clicking on the "spatial browsing" button on the right and not the button on the left.
