Buy in-store, ship to customer orders API field

[UPLONE]

Is there a JSON field or API field specific to the ability to use the POS to "Buy in-store, ship to customer orders"? If so, can you tell me the name of the field and would merchant need to have POS Pro to make the API call to it? I don't see it here: https://shopify.dev/api/storefront/reference/checkouts/checkout#fields-2021-10

Is it a standard field or maybe it is a customer field? This is a specific function to Buy in-store, ship to customer orders (https://help.shopify.com/en/manual/sell-in-person/shopify-pos/order-management/add-shipping), so I'm hoping it has a specific API field we can use with our app.
