A stage is a component of a larger staged flow in a workflow. Workflows can include multiple stages. To view or edit these stages, you need to edit the workflow definition and make changes. The Stages section displays all stages within the workflow definition, where you can view, edit, delete, publish, or unpublish the staged flow.
You cannot edit or delete out-of-the-box (OOTB) staged flows.
You can view, edit, or delete a stage in the same way as a workflow definition. For more information, see Working with Workflow Definitions.
