I want to create a bot for the website https://juwelierfrei.com/ that gives you suggestions which product suits you best. for this I collect information with 'capture information' 'single choice'. I also store this information in different variables. But how can my bot now search this website and find products that meet the criteria set in the questions? I've been working on this problem all day and I still haven't been able to solve it. Would be extremely grateful if someone could help me.

I'm not sure about prestashop but I know with WooCommerce and Shopify you can do it by querying the Rest API endpoints. See whether prestashop has an API you can access. You should be able to post your query along with variables to it to return results. It may also require additional JavaScript code blocks to format or parse your responses.
