[Woocommerce help] - How can I add section to a product?

Hey guys, hope you're all fine.

I'm running a bookstore website, and I'd like to add a section to encourage people more about the book (the product).

I'd like to add 1 section to each product page (Quotes section).

Example:


Can you help me? I've tried until now a plugin call "Woolentor" but it doesn't have the ability to add a new section.

Never mind, I've just found how.
