I am using create react app, along with react-map-gl. I just need the map to show up on the screen right now but all it does is show the mapbox logo and have a blank space where the map should be.
Here is my main .js file:
    import './App.css';
    import ReactMapGL from 'react-map-gl';
    import React, {useState} from 'react';
    function App() {
      const [viewport, setViewport] = useState({
        width: 400,
        height: 400,
        latitude: 38.958630,
        longitude: -77.357002,
        zoom: 10
      });
      return (
        <div className="TextStuff">
          <ReactMapGL {...viewport}
          mapboxApiAccessToken={process.env.REACT_APP_MAPBOX_TOKEN}>MAPPPPP</ReactMapGL>
        </div>
      );
    }
    export default App;
