Why is my set position (mesh) missing in Visual graph

I am using unity 2022.1.6f1, URP, with visual graph, just installed, version 13.1.8; but I can’t find either set position (mesh), or set position (skinned mesh)

Ok, you need to turn on the experimental operators/blocks, which is located at Edit-Preference-Visual Effect.
It is quite frustrating when there is no documentation on the visual graph page. At least I didn’t find it.
