How to use WithCustomImageOcr when working with kernel memory as a service?

What is the correct implementation for using with tesseract?

[dluc]

To use Tesseract:

• create a new class, e.g. TesseractOcrEngine, implementing the IOcrEngine (code) interface
• customize Service/Program.cs (where we call appBuilder.AddKernelMemory), changing this code:

// ...
appBuilder.AddKernelMemory(memoryBuilder =>
{
    memoryBuilder.FromAppSettings().WithoutDefaultHandlers();
// ...

to

// ...
appBuilder.AddKernelMemory(memoryBuilder =>
{
    memoryBuilder.FromAppSettings().WithoutDefaultHandlers();
    memoryBuilder.WithCustomImageOcr<TesseractOcrEngine>();  // <--- add this line
// ...

• build and run KM service
