Currently our solution is a separate tab in the main navbar in RHDH that enables viewing the sonata workflows, executing the workflows and viewing the results.
This solution doesn’t include integration with the backstage catalog. It’s not possible to view and run the workflows from the backstage catalog.
We would like to provide a solution better integrated with backstage through the catalog. We believe this would bring a better user experience. This is also an explicit customer requirement.

there are two possibilities we are looking at and potentially would like to provide both
1. workflow tab in a component, for running a workflow on a business component
2. workflows are components
