how to wrap the the text in the pdf output file - google-apps-script

Question

I have converted a temporary google sheet to pdf with exportOptions. However, I want to keep the font size for the text fixed. This causes the text in each row to spill over to the next page. I believe using text wrapping might solve that but I don't know what the code for it is and don't know how to use it in the codes either. I am a novice in programming.
I have tried using commands such as font size, wrap, text-wrap, researched using google and read the documentation for exportOptions, blob, and text sizing as well.
const url =
'https://docs.google.com/spreadsheets/d/SS_ID/export?'.replace('SS_ID',
target_ss);
const exportOptions =
'exportFormat=pdf&format=pdf' + // export as pdf / csv / xls / xlsx
'&size=A4' + // paper size legal / letter / A4
'&portrait=false' + // orientation, false for landscape
'&fitw=false' + // fit to page width, false for actual size
'&sheetnames=false&printtitle=false' + // hide optional headers and footers
'&pagenumbers=false&gridlines=true' + // hide page numbers and gridlines
'&fzr=false' + // do not repeat row headers (frozen rows) on each page
'&gid='; // the sheet's Id
const token = ScriptApp.getOAuthToken();
const response = UrlFetchApp.fetch(url + exportOptions + target_sheet_Id, {
headers: {
Authorization: 'Bearer ' + token
}});
var blob = response.getBlob().setName(pdfName + '.pdf');
var newFile = folder.createFile(blob);
No error messages but no change in output either probably because those commands don't apply for the exportOptions format.

Iterate through your cells and set the cell wrap of each cell to true using Range.setWrap(true):
var target_ss = "your-spreadsheet-id";
var ss_sheets = SpreadsheetApp.openById(target_ss).getSheets();
for (var i = 0; i < ss_sheets.length; i++){
Logger.log(ss_sheets[i].getDataRange().setWrap(true));
}
