VR Expansion Plugin

Hello sir, I apologize for disturbing you again.
I wanted to ask, how can I do the animation of the hands when he has not touched anything yet? Do I have to give a separate blueprint in the BP_VRCharacter section in the Grab L/R trigger section?
If the left hand mesh is different from the right hand model, which part should I refer to? I changed the models in bp_VRCharacter and in the graspingHandManny section, but both hands are the right model?
In your opinion, how can I create a different mesh in the hands?
