Get Dataset Refresh History response contains filed "Id" which does not exist in the documentation

[shengdoescoding]

I should, according to the documentation, expect these keys in the refresh history response:
(https://learn.microsoft.com/en-us/rest/api/power-bi/datasets/get-refresh-history-in-group, https://learn.microsoft.com/en-us/rest/api/power-bi/datasets/get-refresh-history)

'endTime', 'refreshType', 'requestId', 'serviceExceptionJson', 'startTime', 'status'

However, currently, I am also getting an 'id' field where the value is of type int, there is no information on what this field is.

Even if it is intentional, why doesn't it use datatype str instead of int to stay consistent with the rest of the api.
