Get User Access Token - Facebook Marketing API

Question

I'm using RestSharp to make a call to the Facebook API and it's returning the App Access Token.

However I need to return the User Access Token instead as I need this to create offline conversion sets using the Marketing API.

I've given the app all the appropriate permissions and I can verify this using the Access Token Tool.

Can someone help? Thanks

public void getToken(string uriauth, string clientid, string client_secret, string redirect_uri)
    {

        RestSharp.Deserializers.JsonDeserializer deserial = new RestSharp.Deserializers.JsonDeserializer();

        var client = new RestClient(uriauth);// + "?client_id=" + clientid + "&client_secret=" + client_secret + "&grant_type=client_credentials");
        var request = new RestRequest(Method.POST);

        //request.Resource = "{request_string}";

        request.AddHeader("cache-control", "no-cache");
        request.AddHeader("content-type", "text/javascript; charset=utf-8");
        request.AddParameter("application/x-www-form-urlencoded", "grant_type=client_credentials&client_id=" + clientid + "&client_secret=" + client_secret, ParameterType.RequestBody);

        IRestResponse response = client.Execute(request);

        if (response.Content.ToString().Contains("access") == false)
        {
            try
            {
                throw new System.Exception("Token API doesn't work");
            }
            catch (Exception ex)
            {
                Dts.Events.FireError(0, "ERROR", ex.Message, null, 0);
                Dts.TaskResult = (int)ScriptResults.Failure;
                return;
            }
        }
        else
        {
            Token returnData = deserial.Deserialize<Token>(response);

            if (returnData.access_token != null)
            {
                access_token = returnData.access_token;
            }
        }
    }
