Basically I use ActionChains to press the "down" arrow key and then manipulate it to my advantage. I'll lay out the basic syntax below:

Out of the box I don't think it is possible as generated codecs optimize for common use case (case classes and its fields). But you can derive codecs and tune their behavior afterwards using transformers.

You can use readNullable and map:
