How does meta=(UsesHierarchy) work?

I was trying to find implementation/source on it, but I don’t really know the ins and outs of macros.

Would it display the properties of a pointer to a class which has that metadata in the details panel(in the fashion of actorcomponents)?

IIRC this is meta for TSubclassOf<>, and shows the available classes in heirachy view in editor instead of in a flat list.

Ah, thank you
