How can I stop my GPT from telling users how to create an identical GPT (I want to put mine in the store)

I’ve tried many ways of making my GPT not answer the question of what makes it different to other GPTs so that if my GPT goes to the store I, users can’t create one like mine by literally being told by my GPT how to do so.

I’ve only managed to make it be vague to the point it users “cannot deduce how to create a GPT like itself” but it still gives more details if asked about it, and even when vaguely responding I think its too revealing.

Is anyone experiencing this issue? Have you managed to solve it? Or is it simply a feature I couldn’t find mentioned online that will role out for users who get my GPT from the store? Any information and suggestions are much appreciated
