Use this operation when an external step is needed in order to continue with the rest of the workflow.
For example - a workflow sends a purchase approval link to the merchant (using Gmail, Slack etc..) and waits for the merchant to click on it before continuing with the rest of the steps.

In this example, the `Customer Messenger` node mimics the email or messaging node.
