WebXRInterfaceOptionalFeatures Property

A comma-seperated list of optional features used by Initialize when setting up the WebXR session.

If a user's browser or device doesn't support one of the given features, initialization will continue, but you won't be able to use the requested feature.

This doesn't have any effect on the interface when already initialized.

Possible values come from WebXR's XRReferenceSpaceType. If you want to use a particular reference space type, it must be listed in either RequiredFeatures or OptionalFeatures.
