Uncaught ReferenceError: jwplayer is not defined in React JS

I am trying to play jwplayer videos in my react project, and as documentation suggested I am adding the below code in my public index.html file:

<script
      src="http://localhost:3000/jwplayer/jwplayer.js"
      type="text/jsx"
    ></script>
    <script type="text/javascript">
      jwplayer.key =
        "+1bANyiZkLQznP2yV8ky+2NgQqiQmMg3/Sc0tJdhWUPtP51/8zGnxqqw=";
</script>

But getting the above refernce error. Is there any way i can resolve this issue or if any one has integrated the Self-hosted jwplayer in their react js projects.
