Get world area of screen capture 2d render target

TLDR I am trying to make a minimap where the clicked location(s) of the widget will be mapped to world location (ignoring the Z value).

On my level I have added a screen capture 2d and have referenced it at the gamemode so I can access it anytime.

My minimap widget looks like that:

And the logic for x and y like this:

I am trying to find out the values I need to plug into out A and out B (Value = screen coordinates of click, in A , B are calculated based on the location and dimensions of “ViewPanel”).

I have made the screenCapture2d save to a target texture (1024 x 1024) and then I’ve made that into a material to use for the widget.

Extra render target info:
