Graphql API orderCreate toUpsert a customer don't work

[MartinJackS]

Hi,

I would like to use the OrderCreateCustomerInput when using the mutation orderCreate of the graphQL api.
For example, when using the example shown in the documentation:

const client = new shopify.clients.Graphql({session});
const data = await client.query({
  data: {
    "query": `mutation OrderCreate($order: OrderCreateOrderInput!, $options: OrderCreateOptionsInput) {
      orderCreate(order: $order, options: $options) {
        userErrors {
          field
          message
        }
        order {
          id
          displayFinancialStatus
          customer {
            email
            firstName
            lastName
          }
        }
      }
    }`,
    "variables": {
      "order": {
        "lineItems": [
          {
            "variantId": "gid://shopify/ProductVariant/43729076",
            "quantity": 1
          }
        ],
        "customer": {
          "toUpsert": {
            "email": "foo.bar@shopify.com",
            "firstName": "Foo",
            "lastName": "Bar"
          }
        },
        "financialStatus": "PAID"
      }
    },
  },
});

 an error is thrown:

Error: Variable $order of type OrderCreateOrderInput! was provided invalid value for customer (Field is not defined on OrderCreateOrderInput)

Can you provide more details about how to use this fields?

Best,
