Generating Google doc from template, needing to link within email - google-apps-script

Question

I have sections of Google scripts below that I have set to generate a new document from a template with variables added from a Google form.
The new document is then converted to a PDF and emailed as an attachment.
What I now also want to do is include a hyperlink to the Google document itself.
I can see DocumentApp.openByUrl is a possible function but just don't know how to apply it.
autoFillGoogleDocFromForm
//e.values is an array of form values
var Timestamp = e.values[0];
var Channel = e.values[1];
var Name = e.values[2];;
var file = DriveApp.getFileById('FILEID');
var folder = createChannelFolder(); // 1st modification point
var copy = file.makeCopy(Channel + ',' + Name, folder);
var newId = copy.getId();
var doc = DocumentApp.openById(newId);
var body = doc.getBody();
body.replaceText('{{Timestamp}}', Timestamp);
body.replaceText('{{Channel}}', Channel);
body.replaceText('{{Name}}', Name);
doc.saveAndClose();
}
Send html email
//Setup embedded image.
var imgID = "IMAGEID"
var imageURL = "https://drive.google.com/uc?id="+imgID;
var imageBlob = UrlFetchApp
.fetch(imageURL)
.getBlob()
.setName("imageblob");
var body = HtmlService.createTemplateFromFile("html");
body.Name = Name;
body.Channel = Channel;
var Blob = doc.getBlob().getAs('application/pdf');
var Email = Email;
var subject = 'Submitted';
var values = e.values;
GmailApp.sendEmail(Email, subject, body, {htmlBody: body.evaluate().getContent(),
inlineImages:
{
imageblob: imageBlob},
attachments: [{
fileName: Channel + ".pdf",
content: Blob.getBytes(),
mimeType: "application/pdf"}]
});
}

You should use getUrl().
I don't know how those two blocks of code are related or where you want to include the URL, but the example in the link above should be pretty helpful. Something like
var doc = DocumentApp.openById(newId);
var url = doc.getUrl();
