How would be the best way to Import public facebook pages to discourse

Hi!,
I would like to import several Facebook public pages and republish same content in a time manner (Daily,weekly). The idea is to allow for people that does not have/want to use Facebook see that content.
I have been testing for the last 2 days several tools like “Facebook Scraper,RSSHub” but still unable to get it working.
I am sure someone here had comes in same situation. I am searching something selfhosted/open source. Could anyone give me a hint?
