How to save pkgdown website locally

I've created a website through pkgdown for a package that is intended for local use within the company I work for. I've built the website with the command pkdown::build_site(), which allows me to see the site it has built, but how can I save this so that others can view the website?

One approach is to use a Netlify drop, which is described here.

Is there any way I can just save it as a html document, as can be done with standard Rmarkdown produced html documents, without having to create an actual online URL? It is of more interest to me to be able to send someone the html document by email for example than a URL link as some of the information is sensitive
