This method initializes the platform features synchronously, running on the thread you initialize on. It takes an app ID as a parameter. It checks for the presence of an App ID, and throws an exception if it is missing. If the necessary credentials are present, it calls the CAPI.ovr_UnityInitWrapper() function to perform the actual initialization.
