Facebook login not working 2020

Under the instructions I found here, I didn’t see any example for the client OAuth settings.

Er, what? The instructions are quite clear.

Set up the Valid OAuth redirect URI field, entering https://discourse.example.com/auth/facebook/callback – obviously, replacing the domain with your site’s actual domain name and matching the HTTPS protocol.
