title: Firebase/Expo: What continue URL do I use to redirect a user into my app?
body: <p>I am using Expo/React-Native in a standalone app and sending a link to a users email that the user needs to click on and get redirected back to my app.</p>
  <p>This is the code:</p>
  <pre><code>auth
    .sendSignInLinkToEmail(&quot;&lt;email&gt;&quot;, {
      url: &quot;&lt;continueURL&gt;&quot;,
      handleCodeInApp: true
    })
    .then((res) =&gt; console.log(res))
    .catch((e) =&gt; console.log(e));
  </code></pre>
  <p>I can't use <em><strong>exp://</strong></em> to get back into my standalone app because Google only allows domains. I've tried using the android package name like: <em><strong>com.company.app</strong></em> but that wont work to redirect. I need to use <em><strong>exp://</strong></em>.</p>
  <p>Does anyone know what I need to do in order to redirect the user back into the application after verifying?</p>
