How would you animate a part in a character like you would with a body part ?

green = hand, red = handle, blue = motor6d ^^

I used custom rig maker and bind the sword handle to the hands But when pressing play they just attach back onto the hands. Is there a way to fix this?

I also tried spawning the character and adding the motor6d into the hands like it is with the dummy.
