How to Retrieve Handler Results When Processing Documents Using KernelMemory?

[rainmakerho]

When processing documents with KernelMemory, how can I obtain the results from handlers such as TextExtractionHandler and TextPartitioningHandler? Are there specific methods or best practices for accessing their processing outputs?

var memoryBuilder = new KernelMemoryBuilder()
    .WithoutDefaultHandlers()
    .WithOpenAITextEmbeddingGeneration(aiConfig)
    .WithOpenAITextGeneration(aiConfig);

var memory = memoryBuilder.Build<MemoryServerless>();
Console.WriteLine("* Registering pipeline handlers...");

memory.Orchestrator.AddHandler<TextExtractionHandler>("extract_text");
memory.Orchestrator.AddHandler<TextPartitioningHandler>("split_text_in_partitions");

var result = await memory.ImportDocumentAsync(
    new Document("inProcessTest")
        .AddFile(@"meetingTranscript.txt"),
    index: "user-id-1",
    steps:
    [
        "extract_text",
        "split_text_in_partitions"
    ]);
//how can I obtain the results from handlers? 
//var extractedText = await memory.Orchestrator.GetResultAsync("extract_text");
//var partitionedText = await memory.Orchestrator.GetResultAsync("split_text_in_partitions");
//var extractedText = memory.Orchestrator.GetHandlerResult<TextExtractionHandler>("extract_text");
//var partitionedText = memory.Orchestrator.GetHandlerResult<TextPartitioningHandler>("split_text_in_partitions");
