Modifying and displaying the Windows Desktop through Unity Program like VR display?

Hello, I am using a program I found online to let me run Unity and then have a clickable Desktop while Unity runs. This is so I can later modify and add to the desktop from a "background" Unity program. Existing code below.

However I am looking to modify the code to make my first changes: I would like to make the desktop, still clickable, be repeated twice on the left and right side of the screen. From there I would like to add perspective warping to the shape of the displayed desktop, similar to a VR headset. This is because I am looking at running this 'virtual desktop mirror' environment directly on a custom VR device.

Running the code below, here is what I currently see, a regular desktop:

And here is what I would like to see, with the desktop portion visible still clickable:

(excuse the poor image, I tried in paint to replicate what a VR distortion would look like.)

How could I go about doing this? Existing code below -

Thank you very much in advance for any help!
