Sceneform-android-sdk: ArCore 1.9 AugmentedFace Vertices around the eyes do not move.

Hi,
I want to detect eye blinking using tracking the distance between the vertices around an eye.

When mouth is opened, I found that the distance between the vertices around the mouth was increasing.
But the distance between the vertices around an eye remains unchanged.

The mesh texture around the eyes does not change when the eyes are closed.
(The texture on lips moves well.)

is eye tracking not implemented yet?

I also want to make sure this feature is supported.
The texture around the eyes does not change with the blinking of the eyes.
