Message Identification when oneOf is expected

[crazyash]

I have an asyncapi, similar to the one below. Is there a standard way to identify the message that we receive in the channel?

For instance, In the below example, how to identify the message sent on test2 channel? How do we know if it's objectWithKey or objectWithKey2?

asyncapi: 3.0.0

  test:
    address: test

    messages:
      objectWithKey:
        payload:
          $ref: '#/components/schemas/objectWithKey'
      objectWithKey2:
