Access the "data" field from Firebase notifcation array

How can i read the field “body” from “data” array?
With the following formula i can retrieve “body” from “notifcation” array.
I need to access the whole array.
Thanks a lot for helping me. :innocent:

LOOKUP(outputs["NOTsent"].event,  "body")
curl --location --request POST '' \
--header 'Content-Type: application/json' \
--header 'Authorization: key=<MyFirebaseServerKey>' \
--data-raw '{
    "to": "<Device Token user sent you from his app>",
    "notification": {
        "sound": "default",
        "body": "test message",
        "content_available": true,
        "title": "Hello from the backend"   
    "data": {
        "sound": "default",
        "body": "test message",
        "content_available": true,
        "title": "Hi!!"

Example from Docs.

Notification and data are not arrays but objects.
Have you tried lookup(data, “body”) ?
