I don't think there's anything you need to do at this point. Your question is still open and two votes away from being closed, and your edit is helpful in pointing out how the potential duplicate does not answer the problem.
I don't think it's necessary nor productive to edit your question for each close vote you receive unless another comment is raised with separate concerns.
Just because your question receives close votes, that doesn't mean it's unanimous. It goes without saying that many people visited your question and didn't vote to close it, and also someone in the close vote review queue voted ‘leave open’ (and I have also done the same).
Your first edit clarifying how it's not a duplicate was good. I'd say leave it and focus on looking for an answer to the question rather than meta concerns. You are always welcome to bring the discussion to Ask Different Chat, whether before or after a question is closed, for further opinions and feedback on your question.
