It's great that you were able to resolve the issue! The reason why the buggy version of your code did not work as intended is that the archive/unarchive function was called multiple times. This caused the email to be archived/unarchived multiple times, which resulted in duplicate emails appearing. By creating a separate button element and attaching an event listener to it to call your archive/unarchive function, you ensured that the function was only called once per click, which resolved the issue. I hope this helps! Let me know if you have any other questions.

In the buggy version of the code, the event listener was attached to the document instead of the button itself. This caused the function to be called multiple times for different elements on the page, leading to duplication of emails. Additionally, the load_mailbox function was being called after the archive/unarchive function, which further added to the duplication problem. In the working version of the code, the event listener is attached to the button element itself, ensuring that it is only called once when the button is clicked. Additionally, the load_mailbox function is only called after the archive/unarchive function has completed successfully, which prevents duplication of emails.
