Associate two different page types

I have a site where I created two custom page types

1. Manufacturer
2. Item

How can I relate those two things. Each “Item” has its own page. At the bottom I want to assign that to a “Manufacturer” so that I can display a logo, location, and link to that custom post type page. And then again on the Manufacturer page I want to list the associated “items”

How can I accomplish this because they each have different data so they are different post types. Also, I use Elementor.
