Power Bi embed report - Invalid Character ` in internet explorer 11

Hi,

I've embeded a power bi report in an IFrame. It work's fine in Chrome and Edge Browsers.

But in the internet explorer 11 facing an issue. I see an error Invalid character ` in the dynamically generated power bi js file in the line 

url = resolvedClusterUri + "/explore/reports/" + config.id + `/modelsAndExploration?preferReadOnlySession=true${window.isMobile ? '&mobileStateEnabled=true': ''}`;

 //below is the method from dynamically generated file
function getModelsAndExploration(config, resolvedClusterUri) {
            if (!modelsAndExplorationPromise || !config.id || config.id.indexOf("-") === -1) {
                // This happens in cases where getModelsAndExploration is not needed, like QnA embed.
                return;
            }

            try {
                modelsAndExplorationFrontLoadStartTime = Date.now();
                var activityId = telemetrySessionId;
                var requestId = 'd3acce88-6b11-4492-9387-aaa478472b11';
                url = resolvedClusterUri + "/explore/reports/" + config.id + `/modelsAndExploration?preferReadOnlySession=true${window.isMobile ? '&mobileStateEnabled=true': ''}`;
                if (config.datasetBinding && config.datasetBinding.datasetId) {
                    url += "&datasetObjectId=" + config.datasetBinding.datasetId;
                }

                var xhr = new XMLHttpRequest();
                xhr.onreadystatechange = function() {
                    try {
                        var status = xhr.status;
                        if (xhr.readyState == XMLHttpRequest.DONE) {
                            modelsAndExplorationFrontLoadEndTime = Date.now();
                            if (isSuccess(status)) {
                                var response = xhrBuildResponse(xhr, activityId, requestId);
                                modelsAndExplorationPromise.resolve(response);
                                modelsAndExplorationRequestId = requestId;
                            } else {
                                if (modelsAndExplorationPromise) {
                                    try {
                                        modelsAndExplorationPromise.reject(xhrBuildResponse(xhr, activityId, requestId, true /*isError*/));
                                    }
                                    catch (e) {
                                        console.error(e);
                                        // Cannot parse an error out of the response
                                        modelsAndExplorationPromise.reject(buildExceptionResponse(activityId, requestId, e, modelsAndExplorationPrefix, status));
                                    }
                                }
                            }
                        }
                    }
                    catch (e) {
                        console.error(e);
                        if (modelsAndExplorationPromise) {
                            modelsAndExplorationPromise.reject(buildExceptionResponse(activityId, requestId, e, modelsAndExplorationPrefix));
                        }
                    }
                }

                xhr.open("GET", url);
                setGETRequestHeadersWithGroupId(xhr, telemetrySessionId, requestId, config);
                xhr.send();
            }
            catch (e) {
                console.error(e)
                if (modelsAndExplorationPromise) {
                    modelsAndExplorationPromise.reject(buildExceptionResponse(activityId, requestId, e, modelsAndExplorationPrefix));
                }
            }
        }

Please help.

Thank you
