How can I create a backoffice nav tab and a custom view to display products?

[nevuz]

Hello. I followed this documentation (https://devdocs.prestashop-project.org/1.7/modules/concepts/controllers/admin-controllers/tabs/) but I can't create a TAB (as a 'Catalog' submenu), my idea is to create a section to display a list of products that are on sale (similar to the native Prestashop product list).

Thanks.
