Spotify API - get request C#

Question

I am trying to get saved tracks from Spotify, what am I doing wrong?

        using (HttpClient client = new HttpClient())
        {              
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
            client.DefaultRequestHeaders.Add("Content-Type", "application/json");

            HttpResponseMessage resp = await client.GetAsync("https://api.spotify.com/v1/me/tracks");

            string responseBody = await resp.Content.ReadAsStringAsync();

            Console.WriteLine(responseBody);
        }

This is a request sample from the documentation:

curl --request GET
--url https://api.spotify.com/v1/me/tracks
--header 'Authorization: '
--header 'Content-Type: application/json'
