BRM2.0 Help

There used to be an article on how to add a Book Now button to a Facebook page but it is not showing up when searching. Can we still integrate BRM with Facebook pages? This article links to a missing BRM article: https://bikerentalmanager.com/facebook/

I was able to find the archived article: https://web.archive.org/web/20200808143640/https://support.bikerentalmanager.com/support/solutions/articles/42000051802-add-a-book-now-button-to-your-facebook-page
