How do I copy one of the gpts I created?

Hi, I created one of the gpt for myself, I want to copy the same features and everything for public. how do I copy? the reason I want to keep mine personal is because I have attached some of the personal information with a pdf.

edit - problem is I have given it so many instructions that I don’t remember which Instruction I have given to make it work like this. is there a way to see the history instruction on gpt builder? if so then only I can copy. otherwise I doubt I can make it work like same again

You must recreate it by copy/pasting the instructions, actions, and re-uploading the files.
