Add pagination to store page

Site URL: https://lobster-piccolo-4fl4.squarespace.com/

I need to add around 340 items to a single store page within my site. They are all part of the same theme and will go on this page: https://lobster-piccolo-4fl4.squarespace.com/antiquarian-books 

Does anyone know a way to add pagination to a store page rather than a single infinite scroll? I'd love to have around 20 items per page and then previous and next arrows with numbers to make the content more manageable.

Thanks

Hello, 

Did you find a solution for this? I'm also looking to add such a feature to my store/product page but so far no luck. 

Any help is appreciated!
