Where can custom buttons in an assignment be created by overriding default action buttons?

Custom buttons in an assignment can be created by overriding default action buttons in the Actions tab of the assignment's flow action rule. This area specifically allows developers to modify the standard behavior associated with the buttons displayed in the user interface during an assignment. By accessing the Actions tab, you can define new actions or change existing ones, enabling the addition of custom buttons tailored to specific requirements or processes within the application.

This focus on the Actions tab allows for a streamlined approach to customizing user interactions and ensures that any changes are directly related to the functionality of the assignment process. The other options do not provide the same level of specificity for customizing action buttons, as they refer to broader areas of the application or are used for different purposes.
