Need to search for multiple PDFs in browser and download

Hi all,

I am new to UiPath and currently working on a project with a tight deadline! Any inputs from your end will help.

Problem Statement: I was successful in opening URLs from excel (used read range and Open browser activity) and the next step is to download files from each of these URLs. Once the URLs are loaded, each of them have pdf files which I want to download after renaming it. Some URLs have just one file and some have more. I assume the best way is to search for .pdf extension and click them but I am unable to figure out the connection. It may work for one page with specified elements but here I need a loop. Attaching the screenshot of what I have for reference.

Any input is valuable. Thanks in advance!
