Данные Google Fit Heart Point

Question

Я пытаюсь получить баллы Heart, используя приведенный ниже Фитнес API. Вот API, который я использовал для извлечения Heart Point из OAuth Playground. https://www.googleapis.com/fitness/v1/users/me/dataSources/derived:com.google.heart_minutes:com.google.android.gms:merge_heart_minutes/datasets/1570029722000000000-1569079322000000000

Я получил данные от API, но как получить баллы Heart для какой даты. Я что-то не так делаю?

Вот ответ, который я получил от детской площадки OAuth.
