So original poster here. Changed from my google account.
I realize that using the Proton Pass or anything you need to decrypt would be too slow for wanting to be a part of the "share menu" process. So it doesnt need to be a whole new app. But a small one, in the same way proton bridge exists.
So an app from proton that when installed it can be "shared with" so it shows up on the devices share menu. And as soon as you share it with this app, it would just itself bring up the same os' share menu. But the URL you provided to this proton solution is now sanitized and cannot be tracked.
