Maybe intresting for other people. Since I searched on this for a long time. But you have to save your cookies also and give it with your next request. First this is how i got my authentication code and hold my cookies in a static variable (in the first time i call this method I give an empty value to token).

    public static CookieContainer CookieContainer;
    public static async Task Post( TRequest requestBody, string path, string token = "")
    {
        var baseUrl = new Uri($"urlFromApi");
        CookieContainer = new CookieContainer();
        using (var handler = new HttpClientHandler() { CookieContainer = CookieContainer })
            using(var client = new HttpClient(handler){BaseAddress = baseUrl})
        {
            client.DefaultRequestHeaders.ConnectionClose = false;
            if (!string.IsNullOrWhiteSpace(token))
            {
                client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", $"{token}");
            }
            ServicePointManager.FindServicePoint(client.BaseAddress).ConnectionLeaseTimeout = 60 * 1000; //1 minute            using (var content = new ByteArrayContent(GetByteData(requestBody)))
            using (var content = new ByteArrayContent(GetByteData(requestBody)))
            {
                content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
                var response = await client.PostAsync(String.Empty, content);
                return await GetResponseContent(response);
            }
        }

    }

After this if I do any request to the api I include the cookies (token is what you get from the first response as a result) public static async Task Get(string path, string token = "") {

        var baseUrl = $"https://innoviris-ai.collibra.com/rest/2.0{path}";
        using (var handler = new HttpClientHandler() { CookieContainer = CookieContainer })
        using (var client = new HttpClient(handler) {BaseAddress = new Uri(baseUrl)})
        {
            client.DefaultRequestHeaders.ConnectionClose = false;
            if (!string.IsNullOrWhiteSpace(token))
            {
                client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", $"{token}");
            }
            ServicePointManager.FindServicePoint(client.BaseAddress).ConnectionLeaseTimeout = 60 * 1000; //1 minute     

            var response = await client.GetAsync(String.Empty);
            return await GetResponseContent(response);
        }
    }
