Xumm QR Scanning returns opened: true twice

While integrating XUMM with my react app, what I did was created a websocket connection that listens to the events.

On opening the XUMM QR using the app the socket returned {opened: true} (expected behaviour)

However, when I signed the QR or pulled the slider, it first returned {opened: true} and then the payload response.

In my opinion only payload response should be recieved in this case, maybe there's an error at my end, not sure or is it an expected behaviour
