sub resource on show page
I have a resource called order, in the backend an order has a line item, however this is not a refine resource in the frontend. How can I show a list/table of line items (specified for that order) when looking at the show page of an order? So for example when I look at order 5, it shows a list/table with line items that part of order 5. the backend url (simple rest) is /orders/:orderId/items/
