Looking for an example of how to search for where a class is used in a BP by using the 'find results' tab in the editor

I’m checking to see if it’s safe to remove an old blueprint class. Right clicking on the class, I use ‘Reference Viewer’ to locate the other blueprints that use the one I want to remove. When I go to a referencing BP, I’d like to use the BP editor’s ‘find results’ tab to locate where the class to be removed is used. Something like Nodes(ClassName=“BP_RemoveMeClass”). Does anyone have an example of the correct syntax? Right now I’m working through the possible permutations from the Docs.
