The eye-tracking configuration of Meta Quest Pro in Unity failed and always showed "eyeTrackingEnabl

I am Unity calls Meta Quest Pro eye tracking function, still cannot enable OVRPlugin.  EyeTrackingEnabled (value constant false), even if confirm the eye tracking equipment support.  The following is the core code: "void Start()"

{

if (OVRPlugin.eyeTrackingSupported)

{

if (OVRPlugin.eyeTrackingEnabled)

{

Debug.Log(" Eye tracking enabled ");  // Never triggered

}

else

{

Debug. LogWarning(" Device supported but not enabled ");  // Always triggered

}

}

else

{

Debug. LogWarning(" Device Not Supported ");  // Never triggered

}

}"

Confirm that the device supports eye trackers, the developer mode is enabled, and eye tracking is enabled in the Meta Quest Link Settings.

The eye tracker can be calibrated correctly through the built-in calibration

Besides, how to call the calibration program in unity?  Because the software I developed has high requirements for eye movement information, I hope that a calibration process can be added for each subject before conducting the experiment.
