How to use the @hpcc-js/other.Comms function in @hpcc-js/other

App.prototype.parseUrl = function () {

                logger.debug(baseUrl_1);
                var result = new comms_1.Result({ baseUrl: baseUrl_1 }, _url.param("Wuid"), _url.param("ResultName"));
                result.fetchRows().then(function (response) { return __awaiter(_this, void 0, void 0, function () {
                    var ddlStr, ddl;
