Download file about admbrowser

I am experiencing a similar problem. I would like to download an octet-stream and simply save it. I am wondering what handler would correspond to a Qt file save dialog.

allow_external_content: True
content_handlers:
  application/octet-stream: ???

I haven't had my head in Qt for a while, but I'm assuming one would need to implement a save dialog and file saving of some sort. I took a quick look over the docs and didn't see anything obvious built in to QtWebEngine.

Given that ADMBrowser is aimed at kiosk / locked down usage, I'd be interested in hearing a use case for downloading and saving files. That's one of the many things I created this browser to not have, though if there is an arguable use case I would accept a PR as long as it was disabled by default.

Here is a use case:
A library thin client with only USB ports provides default access to https://pubmed.ncbi.nlm.nih.gov
The accessible USB port allows to download medical scientific papers in PDF on a USB memory stick.

Here is another one:
ADMbrowser manages the web interface of a router or headless system.
Using ADMbrowser as a dedicated browser in this case provides additional security by preventing keystroke recording attacks. The web interface allows for downloading a backup of the router settings in a proprietary file format.

That makes sense. This is a feature that would definitely be disabled by default, and one would want to be able to secure it to make sure the download dialog doesn't become a back door to browsing the system.
