How to use workflow setting form and how it is differ from UI Script?

How to use this feature of workflow help section is blank on this form!
https://cloud.squidex.io/app/{APPNAME}/settings/workflows

I checked other support articles related to workflow but they are old i think and talking about how to use script with UI to change publishing status. if functionality is still same then what is the purpose of this form. I think you have recently added this feature please explain how to use it ?

Thanks,
