NetworkCredential Equivalent in Postman

What is the equivalent Authentication for a NetworkCredential (C#) in Postman?

The code below works, I was just trying to replicate this C# code in Postman in calling the API, I’ve tried using Basic Auth and NTLM Auth, but didn’t work:

private async Task<HttpResponseMessage> PostAsync(string uri)
        {  
            //just sample dummy credential
            var user ="userA";
            var password ="123456";
            var domain = "DIR";
       
            string body = "[1]"; //some type needed for the api call

            var credentials = new NetworkCredential(user, password, domain);
            var handler = new HttpClientHandler { Credentials = credentials };
            using (var content = new StringContent(body, Encoding.UTF8, "application/json"))
            using (var client = new HttpClient(handler))
            {
                return await client.PostAsync(uri, content);
            }
        }

Sorry, just wanted to ask help here.
