Accidentally deleted site from Cloudflare

I was using these 2 DNS settings with cloudflare, but unintentionally, I deleted the website account, and now it has generated another one:

However, I can’t point to the new nameservers because the service registro.br requires email authentication, but it’s not arriving because it’s pointing to the old nameserver (which we no longer have access to). Is it possible to revert to the old (damien and Hattie) nameservers, or restore the settings before deleting the account?

I almost have the same problem. Have you solved it? If so, how did you do it?
