How does cross_language.cpp_actor_class work?

Hi everyone,

I’m trying to understand if the cross_language capabilities of ray can be used with c++ or not.
Cross-Language Programming — Ray 2.9.1 only shows examples for java integration, but ray/python/ray/ at master · ray-project/ray · GitHub has an implementation for c++, too.

If it is possible, can someone please provide me a (minimal) example that I can start from?
Thank you very much!

How severe does this issue affect your experience of using Ray?
