Chatgpt told me about an annotation called @JsonbPreSerialize and corresponding other annotations as well. It says it is defined in package jakarta.json.bind.annotation, but either I'm blind or that's not true. Where can I find this annotation? I'm using pure jsonb with yasson implementation (which should be ok following chagtgpt).

It also says that annotated methods would be called just before serialisation, which is exactly what I need. I want use this to handle jsonb recursion problems.
