How to display desktop in-game? (Like BigScreen or Virtual Desktop)

Hello, I was interested in including a feature like Virtual Desktop in my VR project.

But I have no idea how to show the desktop to the user, I know there is a experimental plugin for easily displaying the web-browser that I have already used, but I wanted to display everything like in the mentioned apps, BigScreen and Virtual Desktop.

I’m relatively new to UE4, so any guidance how I would approach this will be very helpful, I didn’t find any tutorials about it.

Something news?
