How to pull data (products, categories) through a pivot table in Laravel?

Question

Laravel

There are three tables products (products), categories (categories) and a pivot table connecting them .
One product can be in two categories at the same time. How to pull out all products that are in certain categories? That is, there is an array id category [1, 5, 31] and you need to pull out all the products that are in these 3 categories using it.
I wanted to do this:

categoryIds = [1, 4, 10];
 $products = Product::with(['categories' => function ($query) use ($categoryIds) {
            $query->whereIn('category_id', $categoryIds);
}])->paginate();

Answer 1

You have a relationship described in the category model
Get the category and by the name of the relationship (for example products) get all the products
