@slack/bolt@2.4.0

The new WorkflowStep class gives Bolt apps the ability to offer Workflow Builder Steps from Apps.

Slack users can compose Workflows using steps that your app defines. Your app will create the interface for the user to add or edit their step, with the specific inputs and ouputs it needs. Later, Slack will send an event to your app when it's time to execute that step. Learn how to build using WorkflowStep in the Bolt for JS docs.
