How to add a detail using Script Task

Hello, adding a working detail using a Script task can be a very difficult task. In the detail wizard, there is a list of methods like %CreateSchema%, %DesignSchema% or %SaveSchema% which are used while creating details. Unfortunately, there are no detailed instructions on how to do it. But I can recommend looking at schemas SectionPageWizard and SectionWizard to see how it is done in the Detail wizard.
