How to get the PDFViewerApplication from pdfjs-dist in the latest version?

[vrrashkov]

Hello, I am trying to use PDF.js with pdfjs-dist in React. From my research I found that I have to access PDFViewerApplication and setup everything from there. I saw some examples in the internet that people were accessing this from here.

import { PDFViewerApplication } from "pdfjs-dist/lib/web/app";

But with the latest version the web/app directory does not exist, so I cannot retrieve the PDFViewerApplication. Can someone give me pointers if this was changed/moved and where should I look to retrieve it from?
