Convert Feed Dialog URL

[GoldenPlaya3]

Greetings. The social media buttons are ready in the WP system but there is no profile, only the ready text "site address https://www.facebook.com/dialog/fee...ttps://developers.facebook.com/tools/explorer Twitter was set up directly but Facebook provided such a URL, giving an error and not working. I copied the URL from the window opened on Twitter and pasted it into the Twitter section, but I couldn't get this code to work on Facebook. Similarly, how do I find this URL for Pinterest, Flickr, and LinkedIn?
