json - c# digest authentication to do a post request with SimpleJson in Unity (Ultimaker Jedi Api)

Question

I am trying to remote control the Ultimaker S5 via Rest Api. I ve got GET-requests and the initial POST-request to get the username and password working just fine. The problem I am having is, that any other POST-requests require Digest Authentication. In Python this is quite easy to solve, however I spent the last 3 Days trying to implement it in c# with no sucsess.

This is the code that I use for my POST-requests, however this is without any authentication.

So how can I add the digest authenticaion but still send my wwwForm with my parameters? Every hint and help is highly appriciated! I am just starting to get into coding!

IEnumerator GeneralPost(string URLaddition, string[] PostFieldsNames,string[] PostFieldObjects)
    {
        //string application = "UltiAR" ; 
        //string user = "Adrian" ; 
        
        var totalElements = PostFieldsNames.Count(); //number of post Fields
        WWWForm form = new WWWForm(); 

        string URL = baseURL+URLaddition; //puts together the whole URL
        Debug.Log("URL is "+ URL);

        for(int i = 0; i < totalElements; i++) //fills the WWWform
        {
            form.AddField(PostFieldsNames[i], PostFieldObjects[i]); 
        }
        
        using (UnityWebRequest PostJson = UnityWebRequest.Post(URL, form))
        {
            yield return PostJson.SendWebRequest();

            if (PostJson.isNetworkError || PostJson.isHttpError)
            {
                Debug.Log(PostJson.error);
            }
            else
            {
                Debug.Log("Form upload complete!");
            }
        
            JSONNode POSTJsonAnswer = JSON.Parse(PostJson.downloadHandler.text);

            if(URLaddition == "auth/request") //special case with text response
            {
                ID = POSTJsonAnswer["id"];
                KEY = POSTJsonAnswer["key"];

                Debug.Log("ID is:  " +ID);
                Debug.Log("Key is:  " +KEY);
            }
        }

This is the respone header that I am recieving if I try to do a POST

{
  "cache-control": "no-cache, no-store, must-revalidate",
  "connection": "keep-alive",
  "content-length": "38",
  "content-type": "application/json",
  "date": "Thu, 04 Feb 2021 08:18:59 GMT",
  "expires": "0",
  "pragma": "no-cache",
  "server": "nginx/1.14.2",
  "www-authenticate": "Digest realm="Jedi-API", nonce="03c10f9b3d70e36510547dd9e1dde5bd", qop="auth""
}
