How to download Google Docs version history (easy way, doesn't include how to use the downloaded file)

Run this javascript code with the document open in the browser: https://codeberg.org/dullbananas/google-docs-revisions-downloader/src/branch/main/googleDocsRevisionDownloader.js

Usually this is possible by pasting it into the Console tab in developer tools. If running javascript is not an option, then use this method: https://lemmy.ca/post/21276143

You might need to manually remove the characters before the first { in the downloaded file.
