I got some answers to a similar question here https://lemm.ee/post/45993313

Which reminds me that rss-bridge has a Facebook backend that sometimes works and sometimes doesn’t

https://rss-bridge.github.io/rss-bridge/

I used to have a burner account and a program that logged in to FB with Selenium and converted certain “pages” into RSS feeds. It worked great when it did, but Facebook has a lot of measures against scraping, and I burned out trying to maintain this.

I don’t know a way to read their content without an account, which excludes me from a lot of local events.
