You can modify actions and tiles in the Properties pane. To do this, in the Repositories pane, under the App Builder tab, select the Action that you want to modify. Its properties are displayed in the Properties pane.
The properties depend on the object type. To change them, enter the new properties or select them from the drop-down menus and save the repository.
You can change the system name by right-clicking the card, action, or tile in the Repositories pane and selecting Rename. The system name must be unique within the application.
