I want to make use of the Call History API <https://developer.tizen.org/dev-guide/2.2.1/org.tizen.web.device.apireference/tizen/callhistory.html> on the Gear S, but window.tizen.callhistory is undefined.

I have requested the relevant privileges in my config.xml.

Why is CallHistory unavailable?  It appears to be a standard API.  Is there a full list of what standard APIs are available/unavailable on the Gear S?

Thanks
