I'm sure this is mentioned somewhere, but I can't find it. I've noticed support for Oculus Touch in the various controller profiles etc.--so it is possible to run Snapdragon Spaces apps in the editor using Quest Link?
This sequence hasn't been tested or tried so we wouldn't expect it to work, but if it does then it's not officially supported.
Ah so is there any good editor debugging option? Perhaps by using Unity's MARS/ARSimulator feature?
