How to revoke permission to open links in an app

If you have granted the permission to always open specific links in an app, how do you revoke this permission?

What I've already tried:

1. WebView2.CoreWebView2.Profile.GetNonDefaultPermissionSettingsAsync()
   => No effect.

2. WebView2.CoreWebView2.Profile.GetNonDefaultPermissionSettingsAsync() with all CoreWebView2BrowsingDataKinds enumeration values OR-ed.
   => No effect.

3. WebView2.CoreWebView2.Profile.GetNonDefaultPermissionSettingsAsync()
   => Returns nothing.

4. Delete User Data Folder recursively by means of System.IO.Directory.Delete.
   => Actually removes the permission. But I don't want to do that for several reasons - including the problem that part of the User Data Folder might be locked (e.g. by other instances of my application) and therefore cannot be deleted.

I use version 1.0.2420.47 of the Microsoft.Web.WebView2 nuget package:

AB#50723049

Start with the linked discussion 4479 and the reported WebView2 APIs: CoreWebView2.Profile.GetNonDefaultPermissionSettingsAsync and CoreWebView2BrowsingDataKinds. Compare their behavior with deleting the User Data Folder, and determine whether a supported targeted revocation path is documented or needs to be added.
