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!

I really need dispersion effects in UE too. The dispersion effects gives much more reality on objects, oily water, glass window. Trying to figure out how to do in material editor. Probably have to do it with shader language?

Since I work with jewelry a lot, stuff like caustics and dispersion are really essential to me.
Faking the dispersion effect would be enough for me, but not having it at all is really a dealbreaker.

I have seen some visuals which appear to use RTX raytraced caustics in a way which added dispersion to translucent objects like glass.

But I was only able to find extremely limited resources on this. If anyone knows more, please let me know.
