Cannot create node TextureSampleParameterVolume

Hi!
I’m trying to follow the tutorial Using Volume Textures here Using Volume Textures | Unreal Engine Documentation
but I can’t find TextureSampleParameterVolume.

I have the other parameter types such as TextureSampleParameter2D, see screenshot. Has this been depracated or replaced from 4.21, or am I doing something wrong?

This is in 4.22.3-7053642+++UE4+Release-4.22

I’m a complete beginner trying to evaluate Unreal for a volume rendering application, so forgive me if this is a stupid question.
