I have such an array after import a source:

"objectAttributeValues": [
                    {
                        "referencedObject": {
                            "id": 2074149,
                            "label": "My Service 1",
                            "objectKey": "INV-2074149",
                            "objectId": 2074149
                            },
                            "name": "My Service 1"
                        },
                        "displayValue": "My Service 1",
                        "searchValue": "INV-2074149"
                    },
                    {
                        "referencedObject": {
                            "id": 2669736,
                            "label": "My Service 2",
                            "objectKey": "INV-2669736",
                            "objectId": 2669736
                            },
                            "name": "My Service 2"
                        },
                        "displayValue": "My Service 2",
                        "searchValue": "INV-2669736"
                    }
                ]

I want to get the names - “My Service 1” and “My Service 2” as elements of an array “services”. What a modifier should I use?

Can someone help?
