From the widget configuration page, copy the embed script provided for React.js. This will be a URL that points to a JavaScript file, often accompanied by a script tag (similar to the one you’ve written in your example).
The script will load the widget into the div with the id cooperhire-widget (<div id="cooperhire-widget"></div>). Ensure this matches the data-mount-in attribute of the script to ensure the widget is rendered in the correct place on your page.
