Considering Meta’s WebXR Workflow it’s expected that WebXR experiences are hosted as a traditional site rather than a PWA.
I’m aware of Apache Cordova upon exporting a PlayCanvas project yet Meta recommends Bubblewrap as its used on Android for launching a PWA using a Trusted Web Activity.
I’ve used Cordova in the past but for iOS, essentially I wonder if with extra work is it even possible to get a PlayCanvas experience on the Meta Quest Store? Testing WebXR experiences in the browser is not viable for a commercial product, it must feel native.
