I'm looking for how to embed a PDF file in a web page that will be viewable in the native Android browser / Chrome. If I use something like this:

<object data={'LINK_TO_PDF.pdf'+'#zoom=100&scrollbar=0&toolbar=0&statusbar=0&messages=0&navpanes=0'}
type='application/pdf' 
width='100%' 
height='90%'>
<p>This browser does not support inline PDFs. Please download the PDF to view.</p>
</object>

It works great on Chrome, FireFox, and Edge on Windows. It works great in Safari on iPad (iPadOS) and Safari on iPhone (iOS).

But it does not display on Android.

The files are not publicly accessible, so I cannot use the Google Docs viewer.

PDF.js doesn't seem to help. PDFObject doesn't seem to help. I've looked a bit at ViewerJS.org, but most of its source code has not been updated in 7yrs.

I've seen lots of questions and answers about this, but most of them are old. Surely in 2021, there's a way to do this that works with Android?

(Having to download the file, open it up in a third-party PDF Viewer app, and then close it, switch apps, delete the PDF, and go back to the webpage seems very backwards.)

How can this be done to provide a good user experience on Android?
