Insert hyperlink with variable into google docs using google scripts - google-apps-script

Question

I have a google Form, and the responses populate a response google Sheet, which has a google Script function to generate a google Document using a template.
I am trying to get the address entered in the Form (stored in the response Sheet) to become a hyperlink in the generated Doc.
I have been using the body.replaceText() to replace all the fields I need in the Doc:
body.replaceText("{{Date}}", date);
and its working well, but the address field I would like to become a hyperlink.
I have been trying to do it this way:
body.replaceText("{{Location}}", =HYPERLINK("http://www.google.com/maps/place/'+location+'"));
But that does not become a usable hyperlink, resulting with this in the Doc (please note while it becomes a hyperlink on this page it does not become a hyperlink in Docs):
=HYPERLINK("http://www.google.com/maps/place/myplacenotyours")
I have also tried:
body.replaceText("{{Location}}", location = HYPERLINK("http://www.google.com/maps/place/"+location+));
But this throws up syntax errors.
I have this var:
var location = e.values[2];
So perhaps it better to use that to create another var as a hypertext?
I am now trying:
var loclink = 'Hyperlink("http://www.google.com/maps/place/'+location+'","'+location+'")';
but that doesnt do it either... I'm now starting to think that one can't insert a hyperlink using replace method?
Sorry for the noob question, but I can't figure this out. Can you help me find a solution and put a var into a hypertext link and put that into the Doc as a link?!
Cheers.

Something like this:
function insertLink() {
var pattern = '{{Location}}';
var url = 'https://stackoverflow.com/a/69143679/14265469';
var text = 'how to paste a link';
var doc = DocumentApp.getActiveDocument();
var body = doc.getBody();
var next = body.findText(pattern);
if (!next) return;
var start = next.getStartOffset();
body.replaceText(pattern, text);
body.editAsText().setLinkUrl(start, start+text.length-1, url);
}
