API User Creation does not create Phone Feature

(1) Creating a zoom licensed user with POST https://api.zoom.us/v2/users:

{
  "action": "create",
  "user_info": {
    "email": "jsmith@whatever.com",
    "first_name": "John",
    "last_name": "Smith",
    "display_name": "John Smith",
    "type": 2,
    "feature": {
      "zoom_phone": true,
      "zoom_one_type": 16
    }
  }
}

Calling GET /v2/phone/users/jsmith@whatever.com:

{
    "code": 1001,
    "message": "User does not exist: jsmith@whatever.com."
}

does not create an associated phone user.

(2) Creating a basic user with type=1 and no zoom_one_type POST https://api.zoom.us/v2/users:

{
  "action": "create",
  "user_info": {
    "email": "jsmith@whatever.com",
    "first_name": "John",
    "last_name": "Smith",
    "display_name": "John Smith",
    "type": 1,
    "feature": {
      "zoom_phone": true
    }
  }
}

will create the associated phone user account GET /v2/phone/users/jsmith@whatever.com:

{
    "id": "xyz",
    "phone_user_id": "abc",
    "email": "jsmith@whatever.com",
    "extension_id": "123",
    "extension_number": 10013,
    "status": "activate",
    "calling_plans": [],
    "phone_numbers": [],
    "site_id": "blah..."
}

Why is licensed user creation not producing the phone user too?, as it has been requested with feature / zoom-phone = true.

Our plan is “Zoom Workplace Business Plus US/Canada Unlimited Calling”.

Please advise.
