title: How to check if user is confirmed in AWS Amplify?
body: <p>I have a check to see if the user is already in the DB, which is <code>if (e.name === 'UsernameExistsException') {...</code></p>
  
  <p>I tried this check to see if it would return <code>true</code> or <code>false</code>, but no luck: <code>console.log(await Auth.verifiedContact(this.state.email));</code></p>
  
  <p>How can I check if that user is confirmed or not?</p>
