The Complete System component is a button that duplicates the function of the Complete button of the Agent Desktop application. For more information, see section How to Wrap Up After-Call Work of the Agent Guide. A form can have only one component of this type.
Note: This control is supported in version 5.x for forms created in the Form Builder application version 3.x. For component properties, see Bright Pattern Contact Center Documentation version 3.x.
