How to use Restsharp with a plain text body

I am trying to fulfil this Ebay access token WebRequest

The server expects

HTTP method: POST
URL: https://api.sandbox.ebay.com/identity/v1/oauth2/token

HTTP headers :

Content-Type = application/x-www-form-urlencoded

Authorization = Basic

Request body (wrapped for readability):

grant_type=client_credentials&
redirect_uri=<RuName-value>&
scope=https://api.ebay.com/oauth/api_sc

This is working using a WebRequest as shown

var credentials = "Basic " + Convert.ToBase64String(Encoding.UTF8.GetBytes(clientId + ":" + clientSecret));

var request = WebRequest.Create("https://api.sandbox.ebay.com/identity/v1/oauth2/token") as HttpWebRequest;

request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.Headers.Add(HttpRequestHeader.Authorization, credentials);
            
var formData = Encoding.UTF8.GetBytes("grant_type=client_credentials&redirect_uri=" + ruName + "&scope=https://api.ebay.com/oauth/api_scope");
request.ContentLength = formData.Length;


using (var post = request.GetRequestStream())
{
   post.Write(formData, 0, formData.Length);
}

using (var response = request.GetResponse() as HttpWebResponse)
{
   StreamReader reader = new StreamReader(response.GetResponseStream());
   string result = reader.ReadToEnd();
}

However the following RestSharp request is returning an error

Invalid Request

var resource = "identity/v1/oauth2/token";
var request = new RestRequest(resource, Method.POST);
var credentials = Convert.ToBase64String(Encoding.UTF8.GetBytes(clientId + ":" + clientSecret));
request.AddParameter("Authorization", $"Basic {credentials}", ParameterType.HttpHeader);
request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
var body = $"grant_type=client_credentials&redirect_uri={ruName}&scope=https://api.ebay.com/oauth/api_scope";
request.AddParameter("text/xml", body, ParameterType.RequestBody);
var client = new RestClient("https://api.sandbox.ebay.com");

return client.Execute<T>(request);

The following worked for me, but I'm open to better answers:

var resource = "identity/v1/oauth2/token";
var request = new RestRequest(resource, Method.POST);
var credentials = Convert.ToBase64String(Encoding.UTF8.GetBytes(clientId + ":" + clientSecret));
request.AddParameter("Authorization", $"Basic {credentials}", ParameterType.HttpHeader);
request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
var body = $"grant_type=client_credentials&redirect_uri={ruName}&scope=https://api.ebay.com/oauth/api_scope";
var formData = Encoding.UTF8.GetBytes(body);
request.AddParameter("application/x-www-form-urlencoded", formData, ParameterType.RequestBody);
var client = new RestClient("https://api.sandbox.ebay.com");

return GetResult<T>(client, request);

Note the lines

var body = $"grant_type=client_credentials&redirect_uri={ruName}&scope=https://api.ebay.com/oauth/api_scope";
var formData = Encoding.UTF8.GetBytes(body);
request.AddParameter("application/x-www-form-urlencoded", formData, ParameterType.RequestBody);
