How can you make beautiful pagination in product catalog sections?

Question

1C-Bitrix

Tell me how you can make a beautiful pagination in the sections of the product catalog (required by SEOs)?
Now in the catalog section there is such a picture
stoshin62.ru/catalog/legkogruzovye/?PAGEN_1=3
where PAGEN_1=3 - where 3 is the 3rd sheet of the list of goods in the Light truck tires section
Now the link template is
stoshin62.ru/catalog <section>/? PAGEN_1=3
SEOs want it to be like this
stoshin62.ru/catalog <section>/3
Where 3 is the third page in pagination and should not be specified by the PAGEN_1 variable in the browser line
How can this be implemented? Set a new pattern for processing addresses in the urlrewrite.php file?
