How to get 2D face landmarks from ARCore face mesh?

Question

I am using the ARCore android SDK. It provides the 468 3D vertices relative to the center pose of the face with units in meters.

But when I tried to something else on the corresponding CPU image via frame.acquireCameraImage(), I need the 2D face landmarks.

Could anyone help to point out is there any existing API to get the 2D face landmarks ([x, y] in pixels, like the face landmark TFLite model used by mediapipe) of the current CPU image?

Thanks a lot!
