Post Process Shadow Removal for NVG

Hey all
I’m hoping that someone can help me out. I’ve been stuck on this issue for over a week now. I’ve posted in several Facebook groups and Discord groups with only getting a very small handful of replies none of which sadly have helped.

Here is my issue. I’m trying to make electric binoculars which have an NVG mode and a thermal mode. I’ve already got thermal working but with the NVG mode, I’m having an issue. The issue I am having is with normal NVG’s you don’t normally get a shadow effect unlike what I am getting in my version. I have no idea if its possible to brighten up the shadows, remove them or what but basically without this effect, the NVG mode will not work properly. Below are 2 screenshots. First one of my NVG effect and the 2nd is my PP material. I have tried numerous things, played around with a couple of nodes but cannot get close to the desired effect. Can someone here please help me. To put it simply, I need to be able to see into the shadows as well as the normal areas in NVG mode. Can anyone here please help me?
