WebAuthenticationProvider not opening the browser

[ibb2]

Current behavior

Upon creating a new project and selecting web authentication, clicking the login button does nothing. Even after setting the LoginStartUri for the WebAuthentication property?(not sure what this is called) in appsetting.development.json to the correct oauth url.

I am trying to use Google Oauth 2, I have made a desktop client along with setting up the rest of the authentication in the Google API Console. This is how my LoginStartUri looks:
"LoginStartUri": "https://accounts.google.com/o/oauth2/v2/auth?client_id=1075413216201-njiem6pnakgejlp7ducmimdue9mavu2c.apps.googleusercontent.com&redirect_uri=myprotocol:/authentication-callback&response_type=code&scope=https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email&access_type=offline",

Expected behavior

I expect that clicking the login button would open the web browser so that the oauth login flow could begin.

How to reproduce it (as minimally and precisely as possible)

Create a new project leaving everything as default expect for authentication which is set to web.

Workaround

The LoginStartUri works using Launcher.LaunchUriAsync(uri), except for the callback. But this means handling everything manually instead of utilizing the authentication provided by platform uno.

OK so I tried to testing different target on different platform on my Macbook and Windows PC. I found that the only way the web authentication worked was if I used the packaged version on windows or web assembly. IOS, Android, Mac Catalyst, Desktop (Mac, Windows, and Linux) and Windows Unpackaged the login button did not work. This was for both the .NET 8 and .NET 9 runtime.

Not really sure what I am missing or if this expected behavior? Is this working for other people or am i just setting it up wrong?
