Could you guide me how to get it working? (I can use the following to work with a local spicedb instance:

client, err := authzed.NewClient(
        "localhost:50051",
        grpc.WithTransportCredentials(insecure.NewCredentials()),
        grpcutil.WithInsecureBearerToken("somerandomkeyhere"),
    )

) Would like to know how to work with a permission system run by Authzed.
