How to set shippingAddress flag field and companyName field of an address entity?

The OCC v2 API documentation [1] shows Address creation, update and patch APIs.

One strange thing in those APIs is that the request body [2] does accept neither shippingAddress?: boolean property nor companyName property whereas the response body [3] contains them.
How are developers supposed to set the shippingAddress flag field and companyName field of an address entity to true or false through OCC v2 API invocations?
