OCC connector not showing all properties in mapper

Content

Hi
We are trying to integrate OCC connector with Paypal connector for refund processing.
We are trying to map the transaction id to Paypal  capture id in the mapper but see that paymentGroups node does not show up all the properties of the order.
We have selected return processing in OCC connector.
When we see the webhook response (see attached refund_request.txt), i do see a lot of properties coming in the paymentGroups node, but those properties are not visible in the mapper.

I require the transactionId in order to initiate a refund, which is available in the payementGroups.authorizationStatus.
