FB Integration

I'm currently equipping my share score script with proper Facebook integration. I've been following a tutorial online exactly, but I am never prompted to login or share a post. My button is set to run the Share() function.

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; using Facebook.Unity;

public class ask4LOGIN : MonoBehaviour {

 private const string FACEBOOK_APP_ID = "118943272041914";
 private const string FACEBOOK_URL = "http://www.facebook.com/dialog/feed";
 private int roll;
 private string sent;
 public int finalScore;

 void Awake ()
 {
     if (!FB.IsInitialized) {
         FB.Init();
     } else {
         FB.ActivateApp();
         }
     }

 public void Login() {
     FB.LogInWithReadPermissions();
 }

 public void Share () {
     Login();
     FB.ShareLink(
         contentURL: new System.Uri("https://www.facebook.com/feed"),
         contentTitle: "beCAREFUL",
         contentDescription: "I thought up a witty tagline about larches"
         //picture: new System.Uri("http://www.cashjohnson.net/ico.png")
         //callback: FeedCallback
     );
 }

}
