title: Change default hosting firebase with AWS
body: <p>I am using firebase hosting, but I want to change the url so I have created a domain with amazon (route 53) and it's approved. 
  I created in Route 53 a new register with the value and TXT type that firebase returns me but It still doesn't work.</p>
  
  <p>How can I fix it?</p>
  
  <p>Thank you,</p>
