How is the mouse hovered and bound to the target object?

Hi all

I'm trying to create an audio interaction using jit.phys.body, where when the mouse hovers over an object for more than 5 seconds, the object defaults to the bound target object, such that only operations such as rotating, moving back and forth, etc., can be performed on the object, and the sound changes accordingly, both near and far. If the mouse does not move for more than 5 seconds, it means the binding target object is ended. How do I get the mouse to realize the binding and end the binding to the target object in this process, and how do I create a waiting animation while waiting for 5 seconds?

I'm using it.phys.body because I was looking at jit.phys.body's help to create multiple objects, but wasn't sure if there was another way to accomplish this.
