I'm having trouble getting my icon to show up for any google apps script inside my domain.
Google docs say to write it like this:
var output = HtmlService.createHtmlOutput('<b>Hello, world!</b>');
output.setFaviconUrl('http://www.example.com/image.png');
But there is no guidance on how to use a url for a file in a public folder inside my domain.
My urls look like:
https://drive.google.com/file/d/[googleId]/view?usp=drive_link
And then I get an error message saying my file is the wrong type. If I append &type=.png to my url, the type message goes away, and I see the Google Apps Script icon (white arrow on blue square)
When I inspect the browser, I think I'm seeing the root problem:
Cross-Origin Read Blocking (CORB) blocked cross-origin response https://drive.google.com/file/d/[Google ID]/view?usp=drive_link&type=.png with MIME type text/html. See https://www.chromestatus.com/feature/5629709824032768 for more details.
I did also go down the rabbit hole of trying to specify raw .svg codes and that was totally ignored.
I'm looking for a solid solution in 2023. I see one answer that would be embedding my app into a blank google site. That would work, but I'd like to make it work the way it is designed.
I'm not against some free / cheap hosting for the urls but I do not want to use anyone's ip without permission. I see some other questions, but no solutions that work for this specific problem (self host favicon inside google domain)
favicon for web app doesnt load by apps script
favicon.ico doesn't appear when I deploy application to google app engine
