Converting Feed Dialog URL

[GoldenPlaya3]

Greetings. Social media buttons are ready in the WP system but there is no profile, only a ready text with "site address https://www.facebook.com/dialog/feed app_id=145634995501895 &display=popup &link=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2F &redirect_uri=https://developers.facebook.com/tools/explorer Twitter worked directly, but Facebook provided such a URL, giving an error and not working. I copied the URL from the popup window in Twitter and pasted it into the Twitter section, but I couldn't get this code to work on Facebook. How can I find this URL for Pinterest - Flickr - LinkedIn as well?
