Set a correlation variable for receive task with camunda bpmn 2.0 - bpmn

Question

I am new to the camunda workflow modeller. I am trying to create a workflow with bpmn 2.0 as follows
In the receive task I also added the correlation message as follows
But the workflow is expecting to businessKey or CorrelationKey for receive tasks. Camunda documentation says its possible as per the link
https://docs.camunda.io/docs/1.1/guides/message-correlation/
But I don't any such options could be set in my camunda modeller as shown in my second diagram . Is there a problem with my camunda version I use I am not sure. Due to this I am not able to correlate my message in receive task.
Any help here is much appreciated.
Adding my camunda bpmn also.

Answer 1

Not sure if you already have the answer or not, but the documentation that you refers is camunda 8.0, while yours is camunda 7.
I'm not sure about camunda 8, but in camunda 7, you can correlate with business key or variables.
https://docs.camunda.org/javadoc/camunda-bpm-platform/7.14/org/camunda/bpm/engine/runtime/MessageCorrelationBuilder.html
