Flows
The Flows section is where you manage the subflows of your NicoApp.

Note
TIP – When contacts first talk to your channel, the main flow is run. But here in the NicoApp system the main flow doesn't have any special meaning: it's just like any other NicoApp subflow.
Folders can be used to manage and group subflows.
As for the subflow type:

In the chatbot system, the normal subflow runs in the front end and the workflow runs in the backend. In the NicoApp system, however, they all run in the backend, because NicoApps have no Send Message step or question step.
The Function Flow, in turn, is where you put repetitive tasks so you can call them from any other subflow.
To learn how to use the Function Flow, use how it works in the chatbot as a reference.
