SteamVR is not required for a Quest 2. Please follow these steps:
1. Make sure ‘Oculus’ is selected in the vorpX config app as your headset type.
2. If you want to use the wired version of Oculus Link, connect the Quest via USB
3. Launch the Oculus PC App.
4. Launch Oculus Link (wired) or AirLink (Wi-Fi) in your Quest.
Afterwards your Quest is connected to the Oculus app and vorpX can send images to it via the Oculus PC runtime.
Caveat: AirLink requires a fast Wifi 5/6 connection with low latency. If you are unsure about that, better use wired Link via USB.
