How to draw the gaze information on the video later

Question

Hello.

I have a question about Gaze Information.
What I want to do is to draw the gaze information later on the recorded video.

It was possible to output the following gaze information to a log file without displaying the cursor.
-GazeProvider.GazeDirection
-GazeProvider.GazeOrigin
-GazeProvider.GazeCursor.Position
-GazeProvider.HitPosition
I plan to use these data to draw a gaze information on the video obtained using the DevicePortal.

But is there any other good way?
Or is the one that has already been implemented published?
I would appreciate it if you could teach me a good way.

Thank you.
