I would like to know how to use the ootb Review harness. In my use case, I have a screen-flow or multi-step to collect case information. After the last step (which includes a signature capture control), I continue to a different process and assignment where I want the user to review the case information before submitting it for approval (moving to the next stage). By default, this assignment keeps using the Perform harness.
I know you can specify in the process flow/flow action that when an assignment is not performed you can show the Confirm harness, but I'm not sure about how to use the standard Review harness.
Do you really want to use the Review Harness for this? Because for me it sounds like a sort of confirmation screen and nothing else. If you work with Review Harness, all cases on Review mode will be presenting this specific Harness.
Depending on your requirement, you could also have a copy of your associated sections set to read only. And then you could use these copies on this particular flow action where you do not want any modifications made.
