Walkpaths for workers

Hello.

I am using Factory Flow Simulation Apps to create a simulation of a worker carrying a load between two NC machines.
I want the worker to follow a walkpath instead of the shortest route.

So we tried to set up a walking route for the worker using the [Manage Walkpaths] command. However, after executing the command, I could not select a resource zone to set up.
The resource zones were created using the [Add Resource Zones] command that appears when clicking on the NCmachine.
Walking routes were created with the [Definepathway] command.

Am I doing something wrong?
Can you please tell me how to make the workers walk along the Pathway?
