      taskForm.classList.toggle('hidden')
});

We realize you're looking to get help as soon as possible. Rather than pinging someone directly, which can be considered rude, would you mind joining our Discord and asking your question there? Someone might be more readily available to help.

Hmmm I wonder if we should just click the button in the tests and then assert the modal has the class?

That sure is a valid alternative solution.

However, considering that the regex testing was already implemented in the codebase, I chose to address the issue by updating the regex to handle the edge case.

Let me know if you think we should still update the test logic.

I am extremely sorry @ilenia-magoni, didn't intend to cause any inconvenience. Wasn't aware of the process of review here and might have missed the bot message.
I'll ensure to use the discord platform in the future
