How can we get "PokeAHole" material in UE5.4.2?

Hi! I’m trying to create a Mixed Reality or Aumented Reality app in UE and I need that one material, in theory, it has to be included in the MetaXR plugin, but it’s not there, I’ve tried enabling the display of plugin content in the content browser but it’s nowhere to be found.

Thank y’all in advance!
