GraphQL orderEditAddCustomItem

Hey @tewe thanks for getting back,

For now we have two ids, one shopify_order_id and other is admin_graphql_api_id

so you are saying in mutation

orderEditAddCustomItem(id: "gid://shopify/Order/44136107xxxxx", price: {amount: 300.00, currencyCode: USD}, quantity: 1, title: "MY CUSTOM THINGS") {

I need to pass calculated order id?

if that is the case, then from where I can find that calculated order id.

All I need to do is to add a custom line item in the order.

can you please tell all the steps?
