docs: // NewEnterpriseClient creates a new GitHub GraphQL API v4 client for the GitHub Enterprise
  // instance with the specified GraphQL endpoint URL, using the provided http.Client.
  // If httpClient is nil, then http.DefaultClient is used.
  //
  // Note that GitHub GraphQL API v4 requires authentication, so
  // the provided http.Client is expected to take care of that.
