seeing the tutorials and reading the guide says Passing Variables between Flows In your target workflow, define an input Variable from the workflow properties window. Toggle it ON on the Entry node of the target workflow. Now, on the exit node of the parent workflow, the one that brings the user to the target workflow, match the parent workflow Variable with the target workflow input Variable. Now, when you call the target workflow from the parent workflow, you will see the input Variable in the card. You can pass a value or a Variable to it. but that's not how it's explained. I'm going crazy for that
