Time.timeScale doesn't apply on HandModels

[jinwook31]

Currently, I am trying to develop a VR content with slow motions by using Time.timescale.

For example, the slow-motion must be triggered when the grasp happened. The slow-motion is triggered and applied properly on the cube, however, it doesn't apply on hand models as below image.
The cube moves slowly but the hand moves same..

I'm using LeapHandController and Interaction Manager on the cube. Wrote Time.timescale script and applied on the cubes.
I also tried to apply the time script on the hands but doesn't work.

Could anyone help with this or have some idea why this is happening?? Thank you!!

Our hand assets are designed to accurately reflect the movements of the user's hands is much as possible. This means that the hands cannot be stopped by any virtual object or surface, and likely is resulting in their bypassing your script. In order to achieve the effect that you want, you'll have to record the hand movements and play them back at a reduced speed to animate the rigged hands.
