How to extend parmReportName() in Controller class through COC in D365 FO X++?

   public static void main(Args _args)
    {
        BaseController  controller = new BaseController();
        
        // <GIN>
        if (SysCountryRegionCode::isLegalEntityInCountryRegion([#isoIN]))
        {
            controller.parmArgs(_args);
            controller.parmReportName(controller.getReportName());
        }
        else
        {
        // </GIN>
            controller.parmReportName(_args.parm());
            controller.parmArgs(_args);
        // <GIN>
        }
        // </GIN>

        if (controller.isInBatch())
        {
            controller.parmShowDialog(false);
            controller.batchInfo().parmBatchExecute(true);
        }

        controller.startOperation();
    }

Create extension of "ReturnAcknowledgmentAndDocController " class, through COC trying to customized the code and call my report design.


[ExtensionOf(classStr(ReturnAcknowledgmentAndDocController))]



final class ReturnAcknowledgmentAndDocController_Extension{

public SRSCatalogItemName parmReportName(SRSCatalogItemName _reportName)
    {
        next parmReportName(_reportName);

      // pass new Report here
    reportName = ssrsReportStr(ReturnAcknowledgmentAndDocumentCopy, ReportCopy1);


        return reportName;
    }
}
