Calling FBSDKGameRequestContent: receiving the invite but not the notification in Facebook

Question

I'm sending a Game Request Content with something like this:

FBSDKGameRequestContent *gameRequestContent = [[FBSDKGameRequestContent alloc] init];
gameRequestContent.message = @"My message";
gameRequestContent.title = @"My title";
gameRequestContent.recipients = @[idFacebook];
gameRequestContent.actionType = FBSDKGameRequestActionTypeNone;
FBSDKGameRequestDialog* dialog = [[FBSDKGameRequestDialog alloc] init];
dialog.content = gameRequestContent;
dialog.delegate = self;
[dialog show];

And the recipient can see the invite through https://www.facebook.com/games/activity but not receiving the notification in the top right facebook icon. Why is that?

In the Facebook App I've created the iOS app and the canvas game.

You need to make your app public before anyone could watch the notification on their iPhones.
