Change link attached to an InlineDrawing object - google-apps-script

Question

This question was cross-posted to Web Applications: Help me find my Element in a Google Doc so I can act on it in script?
Here is my Google Doc:
https://docs.google.com/document/d/1TgzOIq0g4DyDefmJIEnqycDITIx_2GNQkpdxMGwtqB8/edit?usp=sharing
You can see a button in it titled ENTER NEW NOTE.
I have been successful at rolling through the elements of the doc to find the table and to replace txt in those areas as needed. But the button here needs to have the URL changed, and I cannot figure out how to do it.
This URL seems to give an idea, but I cannot turn it into my answer since I don't quite understand. Mail merge: can't append images from template
Would someone help me with this to the point of showing the actual code, because I have tried to edit the many examples found about elements, setURL and looking to parent, etc. I just end up with a mess.
I am calling the script from a Google Sheet, to wok on a BUNCH of Google Docs. (I will be running through the spreadsheet to get URL's for the next doc to have it's URL replaced.
Here is as close as I believe I have gotten:
function getDocElements() {
var doc = DocumentApp.openByUrl("https://docs.google.com/document/d/1TgzOIq0g4DyDefmJIEnqycDITIx_2GNQkpdxMGwtqB8/edit?usp=sharing"),
body = doc.getBody(),
numElements = doc.getNumChildren(),
elements = [];
for (var i = 0; i < numElements; ++i){
var element = doc.getChild(i),
type = element.getType();
// daURL = element.getURL();
// Look for child elements within the paragraph. Inline Drawings are children.
// if(element.asParagraph().getNumChildren() !=0 && element.asParagraph().getChild(0).getType() == DocumentApp.ElementType.INLINE_DRAWING) {
var drawingRange = body.findElement(DocumentApp.ElementType.INLINE_DRAWING);
while (drawingRange != null) {
var element = drawingRange.getElement();
var drawingElement = element.asInlineDrawing();
//drawingElement.removeFromParent();
drawingElement.setURL("http://www.google.com");
drawingRange = body.findElement(DocumentApp.ElementType.INLINE_DRAWING);
}
// For whatever reason, drawings don't have their own methods in the InlineDrawing class. This bit copies and adds it to the bottom of the doc.
//var drawing = element.asParagraph().copy();
//body.appendParagraph(drawing);
}
Logger.log(i + " : "+type);
}
Here is my newest iteration that shows in the logs the elements, including the inLineDrawing I want to change...
===========
function getDocElement() {
var doc = DocumentApp.openByUrl("https://docs.google.com/document/d/1TgzOIq0g4DyDefmJIEnqycDITIx_2GNQkpdxMGwtqB8/edit?usp=sharing"),
body = doc.getBody(),
numElements = doc.getNumChildren(),
elements = [];
for (var i = 0; i < numElements; ++i){
var element = doc.getChild(i),
type = element.getType();
// daURL = element.getURL();
Logger.log(i + " : " + numElements + " : "+ type + " " + element);
// Search through the page elements. Paragraphs are top-level, which is why I start with those.
if( type == DocumentApp.ElementType.PARAGRAPH ){
// Look for child elements within the paragraph. Inline Drawings are children.
if(element.asParagraph().getNumChildren() !=0 && element.asParagraph().getChild(0).getType() == DocumentApp.ElementType.INLINE_DRAWING) {
//element.getParent().setLinkUrl("http://www.google.com");
Logger.log(element.asParagraph().getChild(0).getType() + " : " + element.getAttributes());
// For whatever reason, drawings don't have their own methods in the InlineDrawing class. This bit copies and adds it to the bottom of the doc.
var drawing = element.asParagraph().copy();
//body.appendParagraph(drawing);
// body.appendParagraph();
if(element.getParent() !=''){
//element.asParagraph().appendHorizontalRule();
//element.editAsText().appendText("text");
// element.getParent().insertHorizontalRule(0);
}
}
}
}
}

I'm not sure why the setLinkUrl() is not available for InlineDrawing 🤔
If you can replace your drawing with an image (You can download your drawing as png or svg and insert it), you will be able to use setLinkUrl
Here is an example:
function myFunction() {
var body = DocumentApp.getActiveDocument().getBody();
// All inline images as a RangeElement
var images = body.findElement(DocumentApp.ElementType.INLINE_IMAGE);
// select first image, in case your doc has more than one you'll need to loop
var element = images.getElement();
var image = element.asInlineImage();
image.setLinkUrl("www.google.com");
}

Unfortunately the Class InlineDrawing doesn't have methods to access the attached links nor any other to programmatically change it to a InlineImage1. It looks to me that you will have have to make the link changes manually.
