Add stoping or canceling the remote presentation process (OID4VP)

[cvetojevichbojan]

It seems beneficial to be able to stop the presentation process while its executing, from a user perspective.

Here is the problematic usecase that occurred:

• User started a presentation request (via wallet.startRemotePresentation(..uri...))
• The process got hung on one of the steps (30+ seconds due to some network latency, and eventually failed with ConnectTimeoutException)
• User wanted to stop the process before the error event and restart it

Currently the wallet API does not support stopping or canceling the process and we have to block the app UI until we receive the next transfer event.

Hello @cvetojevichbojan

Thank you for raising this issue. At the moment, the API does not support canceling or stopping ongoing processes. However, we recognize the importance of this feature and will review your suggestion to evaluate how it can be incorporated into a future release.
