could not connect oculus quest 2 to pc via webxr, can you tell me step by step instructions

You can open the scene using Oculus Quest 2 as a stand-alone headset by using the Oculus Browser (launched in headset). Or, you can open the scene in Oculus Quest 2 as a PC headset by connecting Quest to PC via Oculus Air Link or Oculus Link. In this scenario, use Firefox or Chrome on the PC.

Your web browser should offer you a VR button in the bottom right corner. After pressing the button, the scene will be switched to the VR mode.
