Run the scenario by clicking βRun onceβ and triggering an event to check if the Lark and CryptoPro integration works as expected. Depending on your setup, data should flow between Lark and CryptoPro (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
