How to reposition accessory

I want to know how to change the position of my ball accessory in my ball throwing pose.

After Appending my accessory to the rig in the pose of raising the hand and the ball flying on the ground

I changed the Vertex Groups to b__R_Hand__ in Object Mode.

However, when I return to Pose Mode, the ball is flying in a different position.

I want to lift the ball a little away from the sim's hand and let it float on the ground in front of sim.

Where should I change the settings?

Or is there a way to convert from accessory to object?

I use the TOOL mod and Cheats to Elevate an accessory made into an object on the ground I want to put.



Thank you.
