Once you hit a certain scale it is probably inevitable that users will want to assign, receive, and manage actions (or events, or triggers) inside the product. "Workflow" or "work management" orchestrates all of the backend activity that ensures actions can be recorded, zip around to assignees, have statuses updated, comments entered, and so on.

There are a few tools out there like Elsa and Microsoft Rules Engine that stay in the backend, but are still fairly rudimentary in nature. So far as I know there's no "plotly" or similar A-tier framework that solves this problem for workflow. Most groups that have done it instantly monetize it with their own front end (Asana, Monday.com, etc.) which makes it difficult to justify the effort to integrate if you are going for a lighter weight application. Hope that helps clarify!
