The mentioned tflite model (palm_detection_lite.tflite) can work in Pose detection.
After some changes to the code of course. It will run at ~13 FPS.
You could improve the inference times by porting the model to int8.
Another (minor) improvement can be running the software on a Rpi without desktop.

Thanks for direction.

at least not crashes but nothing drawing to screen.

I assume
https://github.com/google/mediapipe/tree/master/mediapipe/modules/palm_detection
with
https://github.com/google/mediapipe/blob/master/mediapipe/modules/hand_landmark/hand_landmark_full.tflite

work together to draw fingers
