How to start simultaneous work for an operator and Robot


Currently I’m designing an assembly line with Colaborative robots that will work simultaneously on the product.
On the flow I managed to get the Cobots working first. Now I want to add the operator, but I hit a wall on the implementation. My guess is that I need to create signals for the simultaneous work.

How can I approach this?
