Add-on problem

This is my first post as I’m brand new to Kodi. I’m trying to create my first add-on but with no success. I’ve tried it in both macOS and windows. I’m using a very helpful YouTube video and following it step by step. Everything goes well until I get to the step where you unzip the file and then go back to the box icon at the main menu. When I hit the icon, my named file does not appear so I can’t proceed. Would appreciate any help anyone can provide.

Thank You
