Hello,

Navigate to Product templates – https://prnt.sc/OsC47wk_dBwg, create a template and edit via Elementor then you will see all the necessary elements to make the product page – https://prnt.sc/E5MEqVzBzqmu

Then after creating it, you need to assign that product template for all products in Theme settings -> Single product -> Product builder – https://prnt.sc/n0HcSRl4TcII

Kind Regards
