How to add a featured page on another page?

Hello ,

I want to add the Case Study webpage of https://guardianchem.com/articles/case-study/how-safeguard-al-safely-cleans-aluminum/ to the product page which I think has a template in WordPress. The product pages is not one single page, but have different singles pages with one product on each product page.

For example, if you click https://guardianchem.com/product-finder/, you will find different product displayed there. And after you click any product, you will go to a product page.

Could anyone know how to feature the https://guardianchem.com/articles/case-study/how-safeguard-al-safely-cleans-aluminum/ on the product page?

Thanks in advance!
