If you want to render a pdf file in a react app, there are different options out there. The one that I recently used and would recommend for beginners is react-pdf.

npm install react-pdf

For activating links:
import 'react-pdf/dist/esm/Page/AnnotationLayer.css';

Check out the script example here:
