How to compare MongoDB ObjectIDs?

Question

JavaScript

I have an array of products:

Each product has an _id, I also have a menu object that stores the id of the products:

I tried this way:

products.map(
      (product) =>
        product._id.toString() ===
        menu.products.map((menuProduct) => menuProduct.toString())
    )

But the result is always false. Instead of toString() I tried indexOf(), same thing.
How can I compare id to display a product?
