C# WebAuthenticationBroker stopped working with the new Edge update on HL2

Hello everyone,

with the new update to Edge on HoloLens2 making it chromium-based the WebAuthenticationBroker ([https://docs.microsoft.com/en-us/windows/uwp/security/web-authentication-broker]) stopped working in Unity (Hololens2 Build). For simplicity purposes we can look at the following snippet of code:

         String GoogleURL = "url";
         Uri StartUri = new Uri(GoogleURL);
         WebAuthenticationResult WebAuthenticationResult = await 
         WebAuthenticationBroker.AuthenticateAsync(WebAuthenticationOptions.UseHttpPost, StartUri);

It works if we build a UWP application but not when we use it in Unity. It simply won't open the WebBroker/Edge window. We have already reached out to Microsoft with no luck of a reply so we are relying on help here.

Thank you for your answers and advice in advance.
