How to detect user cancellation when using sendCalls (sync or async)

[toniocodo]

Hi,

I'm in the process of replacing our approval/writeContract (useSimulateContract/useWriteContract) flow with batched transactions using useSendCalls and useWaitForCallsStatus. While the happy flow works great, I'm having difficulties to spot when a user cancels his signature in the wallet and thus ends up the process. I have tried to hook into the different onError callbacks from useSendCalls, useSendCallsSync or useWaitForCallsStatus, but it seems they are not triggered as I would expect.
What is the best way to detect this situation in order to update the UI of my app?
