Securing GRPC .net 8 service

Anyone used AUTH0 securing a .net 8 Grpc service accessed from a .net 8 Blazor Webassembly app? Using VS 2022 and all latest stable packages.
Have no issues logging into auth0 from Blazor, but still having issues with providing token to GRPC and processing in GRPC service. Attempting to use an Authorized Channel rather than sending token with each grpc request in the header/metadata. Samples I’ve seen were using .Net Core 3.x so I’m wondering how different it might be in .Net 8. I did link the API to an application.
