Get records[1].fields.images[1].thumbnails.small.url from attachments (Airtable)

How get this using JSONTools extension?

Here the JSON structure part:

{
"records": [{
        "id": "rec8PvsJGSyrKuobb",
        "fields": {
            "Title": "Title here",
            "Description": "Description here",
            "Images": [{
                    "id": "att3pCMrUf9lZkVPj",
                    "url": "zzz.jpg",
                    "filename": "20200930_140945.jpg",
                    "size": 19333,
                    "type": "image/jpeg",
                    "thumbnails": {
                        "small": {
                            "url": "yyy.jpg",
                            "width": 77,
                            "height": 36
                        }

Got it. It was missing to open the corresponding object inside the Array.
