I'm working on a VR project using Unity 2021.3.6f1 and MRTK 2. I was following Deploying to Quest — MRTK2 to build the project to my Quest 2 headset, however the Quest 2 never shows up under the Android Run Device Menu.

I've checked several pages such as Oculus Quest not showing up in "Run Device" and Quest not seen by ADB DEVICES? Try this., and neither of them work. Quest 2 did show up in my explorer and Quest link functions well, but still, not showing under Unity build nor under adb devices.

When I opened SideQuest, it was showing "Dev Mode Not Enabled". I checked it was on, I switched it to off and on and reboot both the headset and Unity and it still doesn't work. Does any one have similar issue? Any clue or insight will be highly appreciated!
