Searching for usages of new Actor class

It seams that I’ve accidentally used my created c++ class in two places of the game layer (my beginplay is called twice).
But I can’t see any “usages” of the file. I mean in VS I would just press Alt+F7 and with reshaper I would see every usage of the class. Can I make something like this here? And also - is there a way to attach to my c++ class and debug it?
