Amazon Best Seller Scraping

How to?
#1

The Amazon bestseller page (as we all know) shows 50 products on page 1, and then up to 2 pages.
I've been scraping these 100 products, but I'm always failing.
Only 60 products are being scraped.
How can I scrape 100 products?

The issue occurs because the listings are only rendered after a scroll down. You check this by refreshing the page and clicking on the element preview for the links selector.

Here is a reference sitemap with an element scroll setup:
