Some asset nodes doesn't appear at blueprints

I’m trying find this node for save an specified asset via blueprint script, but i cant find it anywhere. Save Asset | Unreal Engine Documentation

Does someone knows how to do that?

Seems many other nodes of asset management also disappear from this list::

Thanks

This nodes seems be part of blutility plugin, them appear after i turn it on.
So just a miss information listing them as part of default engine content
