How to programmatically get Head Gaze position and direction in MRTK3 for Hololens2

Question

I working with a Microsoft Hololens2 and the Windows Mixed Reality Toolkit (MRTK3). I'm trying to programmatically get hold of the current Gaze direction and origin, which is explained here for MRTK2:

void LogGazeDirectionOrigin()
{
    Debug.Log("Gaze is looking in direction: "
        + CoreServices.InputSystem.GazeProvider.GazeDirection);

    Debug.Log("Gaze origin is: "
        + CoreServices.InputSystem.GazeProvider.GazeOrigin);
}

However, how do I do this in MRTK3?

Searched on Windows forums with no luck
