Scraping facebook group content.

First of all, hello everyone.

I am looking for a solution to scrape images/videos of a private group that I own, it is a family small group but with a lot of content and we would like to back it up somehow.

I got myself confused after reading a few topics over the internet, saying that there is no way to achieve this.... which seems a little impossible to me.

I am quite familiar with Javascript/NodeJS.
