How to scrape products when the link is on an other domain?

Hello,
I wish to scrap a page on my Zentrada personal account to create a xls of all bought products. The scrap seems to work fine, each product page is opened, image popup also. But whe I can refresh, the file contains only the product lists. All selectors for the product page are empty.
I think I have understood why : the product list is on https://app.tradesafe.eu/ ........ and links to product pages opens a new page (target = _blank) on an other website with this domain Zentrada - Le grande marché du grossiste en ligne

How can I do that ?

Thanks a lot for your help !
