JPA. How to implement the @ManyToMany relationship?

Question

Java

Formally, there is a connection between the two tables, but the table created automatically includes a composite primary key, which consists of two fields that I connected ... It is impossible to remove the primary key modifier. What am I doing wrong?
IDE Idea (if something depends on it).

OrdersDB.class
...
    private List<ProductsDB> products = new ArrayList<>();

    @ManyToMany
    @JoinTable(name = "ORDER_PRODUCTS",
            joinColumns = {@JoinColumn(name = "id")},
            inverseJoinColumns = {@JoinColumn(name = "id")})
    public List<ProductsDB> getProducts() {
        return products;
    }
...

ProductsDB.class

    inverseJoinColumns = {@JoinColumn(name = "id")})
    public List<OrdersDB> getOrder() {
        return order;
    }
