I’m not exactly sure if you can just leverage on aaname to click on a link, there are other dynamic attributes in a selector. ( others can confirm)
If you have the download links in a row, you can use get children attribute and check if the aaname has “download” keyword in for each loop and click on each download link.
In your case you need to add clipping Left 30(play around) to click activity else robot is not clicking on the link
Next step would be to download the link.
For your reference
