Cannot find Editor Scripting Utilities

Hi everyone!

Im trying to use new Python plugin introduced as experimental in 4.19.
I found Python editor script plugin, but i cannot find plugin entitled “editor scripting utilities” as its written in this post

https://docs.unrealengine.com/en-us/Studio/Python

Thats why i get following error:

LogPython: Error: AttributeError: ‘module’ object has no attribute ‘EditorLevelLibrary’

Im using engine 4.19 downloaded using epic games launcher. Is this plugin listed maybe in source engine?

Thanks!
