Mouse event for download functionality not working in IE

I am trying to implement a functionality to download a pdf file using javascript. My code is not working in IE 11. Any leads are much appreciated. Below is the code I am using.

saveByteArray: function(reportName, byte) {
     
var bytes = new Uint8Array(byte);
var blob = new Blob([bytes], {type: "application/pdf"});
var link = document.createElement('a');
link.href = window.URL.createObjectURL(blob);
var fileName = reportName;
link.download = fileName;
link.dispatchEvent(new MouseEvent('click', {bubbles: true, cancelable: true, view: window}));

}
