Im trying to get the participants data from API response..

                    //Level 1
                    Map<String, Object> MapLv1 = (Map<String, Object>) JSON.deserializeUntyped(parser);
                    system.debug('MapLv1 Conversation Summary ==>'+MapLv1);
                    
                    List<Object> arrayConversationSummary = new list <Object>();
                    for (Object o : (List<Object>)Maplv1.get('participants')){
                        arrayConversationSummary.add(o);
                    }

As you can see, i tried to get the participants array data and store it inside list of object..

this is the response example :

                    }
                }
            ]

but when I check the debug, the participants data start from 'address' not from 'id', and the parsing result only get the address, ani, and aniName from the JSON response.. there`s no Id..

when I put the response to Map, the Id disappeared
