Re: Could you please advise how to set the csv download path? Thanks.

When you click the button, it should prompt and default to the browser's download location.

Note that in 4.3, there's an issue with Firefox in which it fails to prompt. A workaround for that has been committed (you can find it in the nightly snapshot builds - but make sure your browser cache is fully cleared), or you can use Chrome in which it'll work as expected.
