Camunda 8 - flexible JSON processing

Is this feature available in Camunda 8 or just in 7? How to return a full JSON object (with all its nested glory) to Camunda 8 Flow.

Every method am trying from SPIN and Jackson JSON are just serialising the object’s metadata back into the flow at best.

Tried the below resources without luck … pls help.
