This action is to be used with the workflow_run event. It allows for a finer grained response to a workflow run. A workflow run that reacts to a workflow run can only filter by activity types completed and requested and not by the conclusion state. This action will create a repository_dispatch event with an event type that includes the conclusion and has the original payload. By using this action there is no need for conditionals in a workflow run. Set eventNameInEventType to true to include the event e.g pull_request in the event name.

The event type is ${workflowName} - ${event ( optional)} - ${conclusion} and client_payload is the workflow run payload.
