Problem statement

Request and Approve is a very common workflow automation pattern in any intelligent automation solution.

In a typical Request and Approve workflow, we perform the following steps:

1. Person A submits a request.
2. Based on the information, the request will be routed to Person B for review and approval.
3. After the approval is granted or denied, the request will then be routed to Person C to work on (if approved) or routed back to Person A with the result.
