Question How do I make a distorted lens effect on my UI?

Currently I have all of my UI elements 2D like normal, but I want to create a distorted-lens-like effect for the UI, basically making it look 3D. An example that I have is in the UI of a game called Ultra kill, as you can see, rather than the normal 2D style UI it has a depth-like effect. my question is, how can I make my UI have depth?

info you might need:
- The screen resolution I am using for my game is 1980 x 1080, and most of the UI text are from Textmeshpro
- I use the 2019.4 version of Unity
- the scripting language I use is C#
- I have all of my UI placed in an empty object
- some of the UI have scripts assigned to them

I have searched all over the internet for tutorials on how to make this effect, but I cant seem to find anything. Can anyone help me? thanks.

 

So, I'm sure you don't need this anymore, but I think if you have a camera that has its layers set specifically to the UI and then set it to a subcamera of the main one and made the FOV of said subcamera really high, that might work. Not sure though, gl. Also, based Ultrakill player

 

this might shock you, but they're just rotated.
