Modifying the auto generated emails that Cpanel creates NOT AUTORESPONDERS

Hello everyone. We are needing to modify the emails that are being created by the cpanel and being sent to new email users. When you create a new email account and you select " Provide alternate email " it sends the email that you can see that I have attached. We want to modify the email that is sent to the alternate email so the user can provide a password for their new email account.
