title: React Google Maps API (ReferenceError: google is not defined)
body: <p>I'm using <a href="https://www.npmjs.com/package/@react-google-maps/api" rel="nofollow noreferrer">react-google-maps/api</a> node module. I need to set the value of <code>zoomControlOptions</code> is <code>TOP_LEFT</code> but I ended up getting this error <code>Uncaught ReferenceError: google is not defined</code>. Here is the <a href="https://github.com/bablukpik/react-google-maps-api-clustering" rel="nofollow noreferrer">link</a> to the repo.</p>
  <p>I'm getting the error here</p>
  <pre><code>const options = {
    zoomControl: true,
    mapTypeControl: false,
    minZoom: 2,
    streetViewControl: false,
    zoomControlOptions: {
      position: google.maps.ControlPosition.TOP_LEFT, // google is undefined here
    },
  };
  </code></pre>
  <p>Please help me :)</p>
