WebView Extensions with Buttons

[markusschaber]

While https://learn.microsoft.com/en-us/dotnet/api/microsoft.web.webview2.core.corewebview2profile.addbrowserextensionasync allows us to load browser extensions, and https://learn.microsoft.com/en-us/dotnet/api/microsoft.web.webview2.core.corewebview2browserextension provides some information, how can we get information about the buttons the extension provides for the browser toolbar, so we can display appropriate buttons in our UI?

Is there a workaround to emulate those buttons if we have more detailed information about a specific extension?

About the use case: We want to support password managers and authentication plugins like KeePass or BitWarden. Our application contains functionality to connect to specific devices on the network(1), and we have no business in implementing a passwort manager on our own.

Additionally, some IT departments (including our own) have policies mandating the use of specific password managers, so we also cannot rely on the built-in Chromium password manager in all cases. Depending on the IT policy, we're required to specifically disable CoreWebView2.IsPasswordAutosaveEnabled. Certifications like ISO-27001 and TISAX tend to come with those kinds of requirements.

It works fine in the client-server setup, where we just rely on the existing, conforming configuration of the browser, but it breaks down for our desktop application using WebView2.

FootNotes:
(1) Think IOT devices and old, established, proprietary protocols - the devices often don't even offer any http(s) services, so OAuth and OpenID connect cannot be supported.
