How to adjust the position and rotation of the prefab HandLandmarkSet to fit with the model?

Thanks for your project. When i use custom model, I can't align the HandLandmarkSet with model, thus can't achieve the result with your default model, Can you tell me how to adjust the position and rotation of the prefab HandLandmarkSet to fit with the model? thanks!
Also，is the tracking result sensitive to the model initiall pose？
