title: Laravel mail with g suites and XOAUTH2
body: <p>I have a g suites account and applications associated with my e-mails. I was looking at the Laravel mail functions but I do not see any option to log in to gmail smtp with xoauth auth type.</p>
  
  <p>I was using PHPMailer with codeigniter and I had to use clientId, clientSecret and refreshToken to send emails via smtp.gmail.com</p>
  
  <p>Is there any chance I can authenticate using xoauth with native laravel swiftmailer?</p>
