Save and Activate the Scenario
After configuring Harvest, Lark, and any additional nodes, don’t forget to save the scenario and click "Deploy." Activating the scenario ensures it will run automatically whenever the trigger node receives input or a condition is met. By default, all newly created scenarios are deactivated.

Depending on your setup, data should flow between Harvest and Lark (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
