Ultimate Facebook Configuration for Page

Hello, we went through the tutorial to configure the UF plugin and created the facebook app for a client. However the tutorial was from a few years a go and did not have any information about specifying a specific page from different pages managed by a business account. So we have enabled support access on the site and the facebook page we are trying to connect is https://www.facebook.com/whyldgirl/ . Please let me know what information you need or what you need me to do on the backend to get it working with that page. Thanks!
