`main_scene`

In the Web App Manifest of a WebSpatial App, this new field can be used to configure the initialization properties of the Start Scene.

Temporary prefixed manifest key

Because this is a new property added by WebSpatial API to the Web App Manifest standard, it needs the xr_ prefix before standardization is complete, so main_scene must be written as xr_main_scene.

The following initialization properties are supported:
