Authentication Scheme and Authorization policy Registration in Startup in Azure Function V2

Can we register Authentication Scheme and Authorization policy in startup which inherits **FunctionsStartup**. While I am trying, I am getting below exception.

**Microsoft.AspNetCore.Authentication.Core: No authentication handler is registered for the scheme 'WebJobsAuthLevel'. The registered schemes are: AADScheme. Did you forget to call AddAuthentication().AddSomeAuthHandler**

Start by reproducing the reported exception when registering an authentication scheme and authorization policy in a FunctionsStartup for Azure Functions V2, paying attention to the AADScheme and WebJobsAuthLevel names in the message. Done means the custom scheme and policy can be registered without the missing-handler exception.
