        // Initialize the client
        IChalkClient client = ChalkClient.Builder()
            .WithClientId("your-client-id")
            .WithClientSecret("your-client-secret")
            .WithEnvironmentId("your-environment-id")
            .Build();

        // Query features
        OnlineQueryResult result = await client.OnlineQueryAsync(new OnlineQueryParams
        {
            Inputs = new Dictionary<string, IList<object?>>
            {
                { "user.id", new List<object?> { "user123" } }
            },
            Outputs = new List<string>
            {
