When running locally we have multiple functions running and we are using the extension AddDurableTaskClient so we can inject this to start orchestration functions:

services.AddDurableTaskClient(b =>
        {
            b.UseGrpc(grpcConfigure =>
            {
                grpcConfigure.Channel = GrpcChannel.ForAddress($"http://localhost:{PORT}");
            });
        });

How do we change the port so that one function can run GRPC on a different port to another function? When we try overriding the port we get connection errors from the GRPC framework.

This only affects us locally when developing as we can't have more than one function running at the same time but we would like to work around that limitation.
