        Unlike simply reading cubbyhole/response (which is deprecated), this endpoint provides additional validation
        checks on the token, returns the original value on the wire rather than a JSON string representation of it, and
        ensures that the response is properly audit-logged.

        Supported methods:
            POST: /sys/wrapping/unwrap. Produces: 200 application/json

        :param token: Specifies the wrapping token ID. This is required if the client token is not the wrapping token.
            Do not use the wrapping token in both locations.
