How can I Convert date from 'Mon Jun 05 2023 00:00:00 GMT+0100 (British Summer Time) to 'DD-MM-YYYY' in google APP Script

function onOpen() { const ui = SpreadsheetApp.getUi();const menu = ui.createMenu('TRIGGER');menu.addItem('create new doc' , 'createNewGoogleDocs');menu.addToUi();} function createNewGoogleDocs() {const googleDocTemplate = DriveApp.getFileById('1l6GsQsIZ5XhfhWFi_RcX5ea-8Zh8DvGd28QugNxCeZo');const destintionFolder = DriveApp.getFolderById('1Jzbk9pPAQTXRuvC9_5rFYoRIV0kbsf4c');const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('CompletedForms');const rows = sheet.getDataRange().getValues();const copy = googleDocTemplate.makeCopy('${rows[0]}, ${rows[1]}',destintionFolder);const doc = DocumentApp.openById(copy.getId())const body = doc.getBody();body.replaceText('{{Clinician}}',rows[1][0]);body.replaceText('{{Date}}',rows[1][1]);body.replaceText('{{Name}}',rows[1][2]);body.replaceText('{{DOB}}',rows[1][3]);body.replaceText('{{Address}}',rows[1][4]);body.replaceText('{{EpisodeID}}',rows[1][5]);body.replaceText('{{PresentingProblem}}',rows[1][6]);body.replaceText('{{PhysicalExam}}',rows[1][7]);body.replaceText('{{USSReport}}',rows[1][8]);body.replaceText('{{Image1}}',rows[1][9]);body.replaceText('{{Image2}}',rows[1][10]);body.replaceText('{{Image3}}',rows[1][11]);body.replaceText('{{Image4}}',rows[1][12]);body.replaceText('{{Image5}}',rows[1][13]);body.replaceText('{{Image6}}',rows[1][14]);body.replaceText('{{Image7}}',rows[1][15]);body.replaceText('{{Image8}}',rows[1][16]);body.replaceText('{{Diagnosis}}',rows[1][17]);body.replaceText('{{Injection}}',rows[1][18]);body.replaceText('{{Drug1}}',rows[1][19]);body.replaceText('{{Drug2}}',rows[1][20]);body.replaceText('{{Drug3}}',rows[1][21]);body.replaceText('{{Drug4}}',rows[1][22]);body.replaceText('{{Reaction}}',rows[1][23]);body.replaceText('{{Plan}}',rows[1][24]);doc.saveAndClose();}
