Can NetworkServer.Spawn() spawn a parent prefab with a bunch of child prefabs?

I'm just curious if NetworkServer.Spawn() can spawn in prefabs with child prefabs. And if it can, where in the documentations does it tell us how to spawn them?

I've been looking everywhere, and it's giving me the impression that NetworkServer.Spawn() cannot spawn these parent prefabs. If I can get a confirmation, it would be nice to know.
