我们可以在Mailable类中使用MailMessage接口吗？

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Mail\Mailable;
use Illuminate\Mail\Mailer;
use Illuminate\Mail\MailMessage;
use Illuminate\Queue\SerializesModels;

class WelcomeEmail extends Mailable
{
    use Queueable, SerializesModels;

    public function build()
    {
        return $this->from('noreply@example.com')
                    ->subject('Welcome to our website')
                    ->view('emails.welcome')
                    ->with([
                        'name' => 'John Doe',
                        'username' => 'johndoe123',
                    ]);
    }
}
