returnFields supported by Search conversations

[Dileep_kaRanki]

Regarding Search conversations
I have provided the returnFields as conversationId and participantData but it is returning all fields.

{
  "query": [
    {
      "type": "DATE_RANGE",
      "fields": [
        "startTime"
      ],
      "startValue": "2024-09-10T12:00:00.000Z",
      "endValue": "2024-09-16T14:00:00.000Z"
    }
  ],
  "returnFields": [
    "conversationId",
    "participantData"
  ]
}
