Comment Moderation Links in Email Throws 404

As a matter of security practice, I install a plugin which changes/hides the default admin login location from “https://somesite.com/wp-login.php” to say “https://somesite.com/_hellokitty”.

However, when I do this, any email that is WP generated to the site owner that contains links back to, say a comment moderation approval, returns a 404 page. The links always start with https://somesite.com/wp-admin/comment.php?action=approve&c=4#wpbody-content

My sense is that there needs to be an NGINX rewrite inserted so that it will change from …/wp-admin/… to …/_hellokitty/…

Question is, what would be the syntax for the rewrite?

Thanks for your assistance.
