The detailed view of a workflow automation is where you can configure its behavior and the various automation processes.
The settings will greatly differ from one Workflow automation to the other, generally however the workflow settings will require the selection of a Form / Web page / Email / Stage name to work properly.
Workflow automations can be linked to one another, for example in the case of a Registration & a Pre-arrival workflow automation: When the participants have submitted their registration forms, they can be automatically placed in the Pre-arrival stage, where they can do other things or see other content pages.
