Replacement for WithAppOnly in v5.

Hi,

I'm using delegated permissions and it seems we could previously use https://learn.microsoft.com/en-us/dotnet/api/microsoft.identity.web.baserequestextensions.withapponly?view=msal-model-dotnet-latest to perform a call using just the app credential. Is there something to do that with v5 ?

Or do I need to do something such as registering another GraphServiceClient instance ?
