Create Worker Phone using REST API - CountryCodeNumber is defaulted

Summary:

When using:

Operation: POST

/hcmRestApi/resources/11.13.18.05/workers/{workersUniqID}/child/phones

Country code is getting defaulted. However, if I use HDL, I can pass blank value in for country code and even from application country code is a non mandatory attribute.

How can we achieve the same behaviour using REST API?

I don't want Country Code column to be populated if I am not explicitly passing it.
