I'm still not understanding how the Playbook itself is updated/edited? I have multiple workflows with KB Articles associated with them and I don't see the Playbook showing up on 'Phishing' SIR's reflecting what is in place in the workflow?

So for instance, how would I add tasks(not the manually added '+ Add Task shown', but actual automated tasks) to this Phishing Playbook? The Phishing workflow has a totally different 'Create Task' steps associated with it then what is showing here?
