dataTransfer is null when creating drag event programmatically

Question

I am trying to create a dragEvent and fire it programmatically using this code on Chrome:

var ev = document.createEvent(\"MouseEvents\");
ev.initEvent(

Looks like it can work like this:

const dataTransfer = new DataTransfer;
dataTransfer.setData("data", '1');
cell.dispatchEvent(new DragEvent('drop', { dataTransfer: dataTransfer }));
