Can't submit facebook app for review

I’m trying to submit my app for review with publish_action.

I keep getting the following error:

“It looks like you haven’t made any API requests to access content with the publish_actions permission in the last 30 days.”

I’m publishing posts to the users’ feed with Facebook SDK for Unity.:

 FB.Feed(link: LinkToApp);

I’ve filled all the necessary fields.

I posted both from the Graph and from an iOS device and I still get the same error when I try to submit for review.

What is missing?

public void FBLogin()
{
    FB.Login("email, publish_actions", AuthCallback);
}
