How to remove unused assets with Editor Utilities?

I am trying to remove unused assets in content browser by using Editor utility widget. But i am not able to find node like (Find references for selected Asset). Can anyone guide me which node matches my requirement

Worked for me:
#UnrealEngine Python Scripts - 4 - Delete Unused Assets

You can report unused assets and delete unused assets.

Hey That is fine but the logic is working from a python script. But i am trying to make the same thing in editor utilities
