This looks super promising, thanks for sharing

Maybe it can be integrated into prospect mail?

I don't have experience with Electron apps but as long as the following conditions are met, it could work.

• Is it possible to install an extension inside the embedded Chromium? Unfortunately, the necessary "Microsoft S/MIME" extension is not available in the official Chrome Web Store but at a custom repo (https://outlook.office.com/owa/SmimeCrxUpdate.ashx, see README.md), which may make the things a bit difficult.
  • Since it's just a proxy for the locally installed Native Messaging host, it may be possible to re-implemented it under a free license and bring it to the Chrome Web Store.
• Do Electron apps look into the same directory for Native Messaging hosts as a regular Chrome (/etc/chromium/native-messaging-hosts/)? Can they use native messaging in general?

I would definitely be interested in implementing this together.
