title: useAuth0().user doesn't show the user Roles
body: <br>
  I am having issues to get a Auth0 user Roles when I call the `useAuth0().user` react hook.
  <p>At the moment I am getting this:<br></p>
  <pre><code>    email: &quot;myemail@test.com&quot;
      email_verified: true
      name: &quot;BB&quot;
      nickname: &quot;BB&quot;
      picture: &quot;https://...&quot;
      sub: &quot;auth0|ABC123&quot;
      updated_at: &quot;2021-02-17T17:24:17.989Z&quot;
  </code></pre>
  <p>In the Auth0 dashboard, I have my user setup with an 'Admin' role and I am trying to set 'Rules' in order to pass the 'app_metadata' to the API response.
  I have seen a bunch of scripts to get the Rules, but none of them works.</p>
  <p><code>context.authorization.roles</code>, tested in the Auth0 create <code>Rules</code> test script window, always returns undefined.
  I am wondering if I am entering the namespace attached to the tokenID incorrectly. At the moment is the URL of the dev page I am using to access to login page. Is that correct? (https://dev-fkjer8938 etc....).</p>
  <p>In theory I should be able to see:<br></p>
  <pre><code>&quot;app_metadata&quot;: {
      &quot;roles&quot;: [
          &quot;admin&quot;
      ]
  },
  </code></pre>
  <p>Your help is much appreciated.
  Joe</p>
