Can't see C++ classes in editor

Hey, I’m unable to see any c++ classes in the content editor window. I have the View Options > 'Show C++ Classes` option enabled but I still only see the Content folder. I’ve added C++ classes via File > New C++ Class and have tried regenerating project files and clean build in visual studio but still can’t see any of the classes in the editor. Thanks for any help.

do you ues 5.3?
