title: apply google optimize with react-gtm-module in reactjs
body: <p>my project're using ReactJS and I applied <strong>react-gtm-module</strong> for GTM implement before</p>
  <pre><code>import TagManager from 'react-gtm-module';
  
  TagManager.initialize({
    gtmId,
    dataLayer: pickBy(dataLayerLocal, (value) =&gt; !isNil(value)),
  });
  </code></pre>
  <p>now, I'd like to implement <strong>google optimize</strong> into the project.
  As I checked on the google optimize, I should inject the google optimize js file (with optimize ID) right after injecting the gtm js file</p>
  <p>but I didn't inject the gtm js file (instead, I used <strong>react-gtm-module</strong> as above)</p>
  <p>My question is &quot;Is there any way that I can apply <strong>google optimize</strong> with <strong>react-gtm-module</strong> ? Or I have to inject gtm and google optimize js file to apply it?&quot;</p>
