Google Apps Script - send email automatically from spreadsheet on shared drive - google-apps-script

Question

[Edited]
I'm using Apps Script in Sheets to use info from a form to, when the form is submitted, populate a template, create a PDF file, and then automatically email the PDF to an email address created from information on the form. The form, the spreadsheet, and the template in a folder on a shared drive.
I get the following error: "Exception: Cannot use this operation on a shared drive item" at tempFolder.removeFile(tempFile). When I deactivate that line of code the script works perfectly. I assume it has something to do with permissions on a shared drive, but am not sure how to set it up to allow me to delete that temporary file. I'm very new to coding, so forgive me if this is a stupid question.
Here is my script:
const info = e.namedValues;
const pdfFile = createPDF(info);
const entryRow = e.range.getRow();
var caseEmail = e.namedValues['LegalServer Case Number']+"#fls.legalserver.org";
const ws = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("With Links");
ws.getRange(entryRow,8).setValue(pdfFile.getUrl());
ws.getRange(entryRow,7).setValue(pdfFile.getName());
sendEmail(caseEmail, pdfFile);
}
function sendEmail(email,pdfFile){
GmailApp.sendEmail(email, "Screening Form","Screening Form Attached",{
attachments: [pdfFile],
name: 'Info'
});
}
function createPDF(info){
const pdfFolder = DriveApp.getFolderById("idforpdffolder");
const tempFolder = DriveApp.getFolderById("idfortempdocfolder");
const templateDoc = DriveApp.getFileById("idfortemplate");
var caseEmail = info['CaseNumber'][0]+"#email.org";
const newTempFile = templateDoc.makeCopy(tempFolder);
const openDoc = DocumentApp.openById(newTempFile.getId());
const body = openDoc.getBody();
body.replaceText("{casenumber}", info['CaseNumber'][0]);
body.replaceText("{name}", info['Name'][0]);
body.replaceText("{timestamp}", info['Timestamp'][0]);
body.replaceText("{casemail}", caseEmail);
//(others deleted for space)
openDoc.saveAndClose();
const blobPDF = newTempFile.getAs(MimeType.PDF);
const pdfFile = pdfFolder.createFile(blobPDF).setName(info['Name'][0]+" - " +info['Timestamp'][0]);
**tempFolder.removeFile(newTempFile);**
return pdfFile;
}

From It's happening at the second-to-last line (remove newTempFile). I updated the code. Thanks for looking at it. and your updated question, if you want to remove the file of newTempFile, how about the following modification?
From:
tempFolder.removeFile(newTempFile);
To:
newTempFile.setTrashed(true);
By this, the file of newTempFile is moved into the trash box.
If you want to completely delete it, it is required to use Drive API as follows. But, in this case, it is required to enable Drive API at Advanced Google services. Ref And, if you have no permission for writing in the shared Drive, an error occurs. Please be careful about this.
Drive.Files.remove(newTempFile.getId(), {supportsAllDrives: true})
Reference:
setTrashed(trashed)
