Signalr host in "worker project"

It would be nice if there was an example, or at least some notes, on how to host signalr in a "worker project", using webapp servers as clients.
I can't find any info on what aspnetcore signalr package to include to make it work.

At the end i saw this sample:
https://github.com/dotnet/AspNetCore.Docs/blob/main/aspnetcore/signalr/background-service/samples/6.0/Server/Server.csproj

which uses the "Microsoft.NET.Sdk.Web" instead of the "Microsoft.NET.Sdk.Worker" sdk, changed it in the project file and also removed the "Microsoft.Extensions.Hosting" package since it's not needed as this page says:
https://docs.microsoft.com/en-us/aspnet/core/fundamentals/host/hosted-services?view=aspnetcore-6.0&tabs=visual-studio#worker-service-template

It seems to work now, but it would be nice to have official docs about it.
