How to secure uploaded file and access it from an external tool

Hello, We use the ‘file uploader’ in our application. We have tried using the ‘private’ function to secure the URL, and we get this type of link: https://portail-operations.client.com/version-6123s/fileupload/f1717504416555x090224800/Capture%20d%27%C3%A9cran%202024-05-23%20171839.png . However, we would like to know how it is possible to download the document from an external tool. Thank you.
