Convert Feed Dialog URL

[GoldenPlaya3]

Greetings. The social media buttons are ready in the WordPress system but the profile is missing, only the ready text contains "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 was taken care of directly but Facebook provided such a URL, giving an error and not working. I obtained the URL from the popup opened on Twitter and pasted it in the Twitter section, but I couldn't make this code work on Facebook. Likewise, how can I find this URL for Pinterest - Flickr - LinkedIn?
