Info message Yes, No need to popup in sys operation framework

Hi team,

I have created a batch job with Sys Operation Framework. Once user click on Ok, then wants to popup info message like
Are you sue to delete the transaction? Yes or No

If user clicked on Yes then only it will allow to procced. else nothing happen

Controller class

internal final class DeleteBankTenderController extends SysOperationServiceController
{
    public static void main(Args args)
    {
        DeleteBankTenderController sysOperationController = new DeleteBankTenderController();
        sysOperationController.parmClassName(classStr(DeleteBankTenderService));
        sysOperationController.parmMethodName(methodStr(DeleteBankTenderService, operation));
        sysOperationController.parmExecutionMode(SysOperationExecutionMode::Synchronous);
        sysOperationController.startOperation();
    }

    public ClassDescription defaultCaption()
    {
        return "DeleteBankTenderTrans";
    }

}

Pls give me more shed on this.

thanks!
