ios - YouTube Data API Error 403 Insufficient Permission

Question

I'm working on an IOS app using Swift that requires accessing to the user's YouTube subscriptions. After adding all scopes I need on Google Cloud Platform and implementing GoogleSignIn in Firebase. I sign in (GIDSignInButton), then I get the error shown down below after making this request:

https://www.googleapis.com/youtube/v3/subscriptions?part=snippet%2CcontentDetails&mine=true&key=(apiKey)&access_token=(Access_Token).

The Access_Token is the one I got after I call:

    func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error?){
    user.authentication.accessToken
....}

The error I'm getting:

 ["error": {
        code = 403;
        errors =     (
                    {
                domain = global;
                message = "Insufficient Permission";
                reason = insufficientPermissions;
            }
        );
        message = "Request had insufficient authentication scopes.";
        status = "PERMISSION_DENIED";
    }]

In App Delegate I set this:

GIDSignIn.sharedInstance().clientID = FirebaseApp.app()?.options.clientID
