Fail to get MediaPipeNormalizedLandmarks from MediaPipeFaceLandmarkerResult => face_landmarks

[GeorgeS2019]

https://github.com/j20001970/GDMP-demo/blob/3474994c3a844d935551c9793c8b642868105d2e/project/vision/face_landmarker/FaceLandmarker.gd#L37

The FaceLandMarks should returns Godot.Collections.Array<MediaPipeNormalizedLandmarks>

The casting of Godot.Variant to MediaPipeNormalizedLandmarks does not work

func show_result(image: Image, result: MediaPipeFaceLandmarkerResult) -> void:
	for landmarks in result.face_landmarks:
		draw_landmarks(image, landmarks)

func draw_landmarks(image: Image, landmarks: MediaPipeNormalizedLandmarks) 

    public Godot.Collections.Array FaceLandmarks
    {
        get => (Godot.Collections.Array)Get("face_landmarks");
        set => Set("face_landmarks", Variant.From(value));
    }

Please provide a demo for this issue.

Do you have suggestion how to Bind with better performance to get Godot.Collections.Array<MediaPipeNormalizedLandmarks> => in ONE STEP, so iteration can be avoided?

//This step SLOW down the performance significantly <============ var landmarks = GDExtensionHelper.Bind(tmplandmarks.AsGodotObject());

public Godot.Collections.Array FaceLandmarks
{
        get => (Godot.Collections.Array)Get("face_landmarks");
        set => Set("face_landmarks", Variant.From(value));
}

Let's move the discussion to the correct issue (#21) and continue it there.
