Dear All,
How can the visual workflow be seen in the sample approval flow of the latest version 24.2?

Hope to see like this:

Why can't this visual workflow be seen in the built-in examples? It is still the same as the previous lower version, and there is no visual workflow viewing page. Is this considered a Bug? Since the visual workflow function has been provided since 24.1, why hasn't the example been updated yet? Can it enable us to see the visualized workflow? Could Oracle be so careless? Or are there any switch Settings? I can't operate it?
Best regards,
G.H
