title: Set Cognito Verification Type to Link in CloudFormation
body: <p>I'm trying to figure out how I can set the verification type from <code>Code</code> (default) to <code>Link</code> in my CloudFormation template.</p>
  
  <p>In the website I can set it here: <a href="https://i.stack.imgur.com/jHcyo.png" rel="noreferrer"><img src="https://i.stack.imgur.com/jHcyo.png" alt="example"></a></p>
  
  <p>If I take a look at the <a href="https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-cognito-userpool.html" rel="noreferrer">docs</a> there is nothing mentioned.
  My CloudFormation looks like </p>
  
  <pre><code>SomeUserPoolResourceName:
    Type: AWS::Cognito::UserPool
    Properties:
      UserPoolName: SomeResource_User_Pool
      EmailVerificationType: Link  # I want something like this
      EmailVerificationSubject: 'Your verification link'
      EmailVerificationMessage: 'Please click the link below to verify your email address. {##Verify Email##}' # fails because {####} is required
      AliasAttributes:
        - email
      AutoVerifiedAttributes:
        - email
      Policies:
        PasswordPolicy:
          - .... 
      Schema:
        - ....
  </code></pre>
  
  <p>Is it possible to configure this via CloudFormation?</p>
