Our store has products with sub-line items that can have custom information. For example, an order can have 5 e-Cards, each e-Card will have fields where a customer can enter custom text information.
On REST, I was able to utilize properties which nested under line_items: Liquid objects: line_item
On GraphQL, this seems to not exist: LineItem - GraphQL Admin
Is there a similar function on GraphQL that I need to be looking at?
