Substrate Material Dispersion Effects?

Hello, I’m pretty new to rendering with unreal. One material property which I can’t figure out is “dispersion”. The splitting of light in its colors when passing though translucent objects.
Commonly known from the rainbow color split in diamonds or prisms.

Dispersion is pretty important to me, especially for rendering path traced cinematic renders.
So if anyone could tell me how to get this effect or where it can be found if they are calling it differently, please let me know.

Thanks for your time and help, I greatly appreciate it!
