Cancel payment authorization

Hi,

I'd like to be able to cancel a payment authorization (before the authorization has completed)
Authorization works fine.
Not sure how to implement cancel authorization when user clicks on "Cancel" button in payment view.
I'm getting the CancelOperationPaymentTerminalDeviceRequest in HardwareStation but not sure how to pass that to payment connector in PaymentSDK & convert it to this:

If Authorization isn't complete yet
{
  PaymentConnector.CancelAuthorization()
}

There's Void, Authoirze, Capture calls in PaymentSDK but not Cancel !

Can anyone help ?

Thank you.
