MetaHuman and displacement in UE5.3

Hello everyone.

I am trying to add displacement on a metahuman character.
Here is the video of what I would like to have :


the first part is the displacement on a simple sphere mesh.
and the second part is the same effects applied on metahuman
but a little tweak : since the displacement option is only on a static mesh with Nanite, I converted for the time being the MH as a static mesh as well.

How would you do to have the same effect on MH?

here is the screen shot of how I did it on the sphere:

on MH, I basically copy-pasted in its material
Any thoughts? thank you!
