Virtual Reality Hand-Grab Collision

For my VR program in ue5.2, I am creating an experience that involves assembling a breadboard circuit. I created my own custom hand animation of the index finger and thumb pinching to look like they are grabbing a wire. However, when I try to grab small things with this custom hand animation it’s very finicky and doesnt always work. How do I just adjust the collision of the hand template in Ue5 to make it where it will only grab objects if it overlaps with that specific part of the hand?
