WebSocket event for ignored/closed sign requests

Hi,

My client side code listens to events/transaction status updates using the WebSocket approach. I noticed that when the user chooses the "Close" button instead of Accept/Decline in the transaction sign request, it doesn't emit/send any event to the websocket connection.

Is there a way to know when the user closes or ignores the sign request? Or will a feature for this be added in future versions?

Thanks
