Is it possible to obtain data on how hard a user is grabbing an object using Leap Motion?

Hi everyone. I am fairly new to Unreal Engine as I only started developing about a month ago using the Leap Motion device. I already have my game set up to have the user interact with an object by picking it up and dropping it, but the way that I am doing this is through a grabbing motion, where the user makes a fist. I want to do it just by using the fingers, like someone is actually holding the object. I then would like to obtain the “pressure” of each finger being pressed against the object (sort of like the “grab strength” function but with finger to object). Does anyone know how I can accomplish this? Or maybe point me in the right direction?
Thank you.
