.NET Maui iOS - System.PlatformNotSupportedException: 'Operation is not supported on this platform.' Google.Apis.Auth.OAuth2

This Library / code works fine in Xamarin Forms latest. I'm working on bringing an App over to .NET Maui and am receiving this error. Is there something about .NET Maui HTTP that is less supported than Xamarin iOS?

Code:

    new SheetsService(new BaseClientService.Initializer()
