How to use functional transforms?

[plutonium-239]

I have seen that all transforms have a "functional name" (for ex., RandomNodeSplit is random_node_split)
However, I can't figure out how to call this functional.
I've tried:

T.random_node_split(...) # TypeError: 'module' object is not callable

I also tried accessing random_node_split inside the only other functional module I know, torch_geometric.nn.functional, but it does not exist there. Neither does there exist a functional module inside transforms.

I have looked around but found no questions/docs on this

The functional_name can be used for DataPipe support in PyG. You can find an example here.
