arModes property
A prioritized list of the types of AR experiences to enable. Allowed values are "webxr", to launch the AR experience in the browser, "scene-viewer", to launch the Scene Viewer app, "quick-look", to launch the iOS Quick Look app. You can specify any number of modes separated by whitespace. Note that the presence of an ios-src will enable quick-look by itself; specifying quick-look here allows us to generate a USDZ on the fly rather than downloading a separate ios-src file.
