How do I download 2 files from JS enabled URL

I’m trying to get the Receipt and Invoice from an URL like this (test) one: Stripe Invoice

I’ve tried using HTTP get but I couldn’t get to the source of that page.
I then searched the forum and found an alternative with ScrapeNinja but wasn’t able to make it work with the scraper.
Would love to understand how to download the 2 files (PDFs) from that page.

Do you have the Stripe information about the invoice and payment? There may be a way to use the Stripe app in Make to get this information rather than getting it from the web page.
