Does UE5.1/5.2 supports creating a volumetric cloud by c++ classes, then how to do it

I have already downloaded the volumetrics plugin, while it seems that the plugin only supports Blurprint. And under plugin file, there is no “volumetric c++ classes”, like “Procedural mesh component c++ classes”. Cuz I used to create a procedural mesh component by creating a new procedual mesh component c++ class and adding “ProcedualMeshComponent” in build.cs file, then it works. Currently, I am so lost in how to create a volumetric cloud. The used way didn’t work now. Can I know if UE 5.1, 5.2 supports creating a volumetric cloud via c++ classes?
