I found out that you upgraded the node last year, but I am unable to determine the NPM package version before the node upgrade.
[Update node js version to 18](https://github.com/cyntler/react-doc-viewer/commit/c778f307958f9d1f701ffe9f45db34ba143743ab)

My node version is 16.20 and cannot be upgraded. Which version should I use?
Please.
