saveAs not working in chrome with iPad and iPhone

We are using docx npm to generate the word document. To save the generated document we are using below code snippet.

Packer.toBlob(data).then((blob) => {
saveAs(blob, filename);
});

saveAs is working as expected in chrome browser in windows and safari browser in iPad and iPhone. However, it is not working when we tried it in iPad and iPhone on chrome browser.
