Envio com cópia - Errata

Boa tarde, não sou muito experiente com php. Estou iniciando nessa área agora!

É o seguinte preciso que o sistema envie um e-mail com cópia para um e-mail específico, já tentei de várias formas e não consigo, segue abaixo os arquivos ultilizados.

Se alguém poder me dar uma força.

Obrigado!

-----------------> UserMailer.php<-----------------------

<?php
namespace Care\Mailers\Swift;

use Care\Mailers\UserMailerInterface;
use Care\User;

class UserMailer extends Mailer implements UserMailerInterface
{
/**
* Send welcome email to new registered users
* @param User $user

 * @return mixed|void
 */
 public function welcome(User $user)
 {
 $view = 'emails.welcome';
 $subject = 'Bem-vindo ao Sistema de Chamados TP Tech';
 $data = [
 'name' => $user->name
 ];

 return $this->sendTo($user->email, $subject, $view, $data);
 }

 public function TicketOpened(User $user)
 {
 $view = 'emails.new-ticket';
 $subject = 'Novo chamado foi inaugurado';
 $data = [
 'name' => $user->name
 ];

 return $this->sendTo($user->email, $subject, $view, $data);
 }
}
