I am using GoogleFit API to fetch the data I have added in the Gooogle Fit app, but it takes around 30 mins or so to get that data reflected in the API response.

API: https://www.googleapis.com/fitness/v1/users/me/dataset:aggregate

Request Body

{
  "aggregateBy": [{
    "dataTypeName": "com.google.blood_glucose"
  },
  {
    "dataTypeName": "com.google.blood_pressure"
  },
  {
    "dataTypeName": "com.google.heart_rate.bpm"
  }],
  "startTimeMillis": 1645446600000,
  "endTimeMillis": 1645533000000
}

Response Body
