Thanks Jordan. Can you briefly explain how I can leverage Nirmata Workflow here? I was going through this example http://nirmataoss.github.io/workflow/example.html but I was not able to understand how can I use it for my use case?
And if you have some other solutions as well which I can use here then let me know as well.
