This doesn't force download if the target file is for example an audio file. It starts playing directly in the browser without any download started :(

Don't forget to add document.body.removeChild(anchor); below anchor.click() line.

A better way will be to show a link in your UI, so the user can click to download
That way is safer from getting blocked
something like:

<a href="attachment_url" download="attachment_url" target="_blank">Download</a>

Remember: This only works if the download url is in the same domain as you application.
