And just to add to what Mimi has said above, in order to access those parameters it is my understanding that you must:
- create a flow that loops on the Collection Element (as seen above, in the parameters section, is the same name as the Artifact Type). Then, within the actions you add to the flow you can access those artifact properties like: Artifact File, Definition Name, etc..
- In order for the above to be available you must assign an artifact version to an artifact package and then the package must be assigned to a deployment.
