undefined method `note_vulnerability_email' for Notify:Class

Implementation plan

• backend extend https://gitlab.com/gitlab-org/gitlab/blob/master/ee/app/mailers/ee/emails/notes.rb#L5 with note_vulnerability_email method with params (recipient_id, note_id, reason = nil):

def note_vulnerability_email(recipient_id, note_id, reason = nil)
  setup_note_mail(note_id, recipient_id)
  add_group_headers

  @vulnerability = @note.noteable
  @target_url = project_security_vulnerability_path(*note_target_url_options)
  mail_answer_note_thread(@vulnerability, @note, note_thread_options(recipient_id, reason))
end
