Hello friends I want pass oauth_token and client_id in request body of a GraphQL Client. So how can I pass them, because GraphQLRequest has only three fields (i.e Query , Variables and OperationName). Please suggest. 
using GraphQL.Client;
var heroRequest = new GraphQLRequest{ Query = Query };
var graphQLClient = new GraphQLClient("URL");
var  graphQLResponse = await graphQLClient.PostAsync(heroRequest);
