Hi Everyone, I have written code to generate pdf, it picking the default Advance/Pdf template but i want it to pick the template based on my requirement, any suggestions?

else {
            try {
                // var tranId = O5329444;
                //var tranId = parseInt(5599467); //{5599467, 5599591}; //

                const tranId = [5599467, 5599591];
                //var customTranTemplateId = 425;
                var transactionFile;
                var renderer = render.create();
                for (var i = 0; i < tranId.length; i++) {
                    
                    transactionFile = render.transaction({
                        entityId: tranId[i],
                        printMode: render.PrintMode.PDF,
                        inCustLocale: true
                        // formId: customTranTemplateId
                    });
                    log.debug("File", transactionFile);
                    
                }
                
                log.debug("File", transactionFile);

                context.response.writeFile({
                    file: transactionFile,
                    isInline: true
                });
            } catch (e) {
                log.error({
                    title: 'Error : ' + e.name,
                    details: e.message
                });
            }
        }

templates are associated with forms
