How to use Body Tracking in MovementSDK to operate bigger characters

I don't want the model to be squeezed or stretched, I want to maintain the body proportions of the original model and perform full body tracking.
But I found that full body tracking can only achieve tracking that is about the same size as my height. A model that is too small or too large can cause tracking anomalies, even if I adjust settings such as Deformation or RetargetingConstraint.
