Amazon.Lambda.APIGatewayEvents.APIGatewayProxyRequest is missing methodArn parameter

The documentation for a REQUEST type custom lambda authorizer shows there should be a parameter called methodArn in the APIGatewayProxy request but I am not seeing in in the class. I’m using the AWS SDK using .net-core3.1. Am I using the correct input class for the function handler or is the methodArn parameter missing?

namespace Amazon.Lambda.APIGatewayEvents
{
   public class APIGatewayProxyRequest
   {
      public APIGatewayProxyRequest();

      public string Resource { get; set; }
      public string Path { get; set; }
      public string HttpMethod { get; set; }
      public IDictionary<string, string> Headers { get; set; }
      public IDictionary<string, IList<string>> MultiValueHeaders { get; set; }
      public IDictionary<string, string> QueryStringParameters { get; set; }
      public IDictionary<string, IList<string>> MultiValueQueryStringParameters { get; set; }
      public IDictionary<string, string> PathParameters { get; set; }
      public IDictionary<string, string> StageVariables { get; set; }
      public ProxyRequestContext RequestContext { get; set; }
      public string Body { get; set; }
      public bool IsBase64Encoded { get; set; }

   }
}

@msimpsonnz I think that will work perfectly. I couldnt find documentation on when to use the APIGatewatyProxyRequest vs the suggested APIGatewayCustomAuthorizerRequest (albeit Im very new to lambda authorizers), is there a better location than the documentation I linked to above?

I appreciate the response!
