title: AWS Cognito: Email verification with Link
body: <p>I'm using Cognito for User Management, and everything seems to work fine apart from email verification process.</p>
  
  <p>I would like to build user journey similar to all other website: 
  1) Fill registration form with user details
  2) Receive an email with email verification link
  3) Verify email address by clicking on the link</p>
  
  <p>So far, I can only verify email by making user manually input verification code. This is slightly unusual. And some users find it easier to just click on the link.</p>
  
  <p>On "Message customisation" page, there is a possibility to use "link" for message verification. But it is using "Amazon Cognito domain", which is exposing underlying technology to the end user.
  Ideally I would like to use my own domain.</p>
  
  <p>I'm trying to "Use own domain" at "App integration->Domain Name" tab, but getting "We didn’t find any AWS managed certificates for this region."</p>
  
  <p>But I have added "AWS managed certificates" for my domain and verified it via DNS. It is appearing in "Certificate Manager" with status "Issued".</p>
  
  <p>Have someone successfully managed to use "Your own domain" for email verification? What am I missing?</p>
  
  <p>Thanks,
  OM</p>
