How do you get Extract Schedule Refreshes data based on a Data Source through the Tableau API?

If you are using the Tableau API to retrieve DataSource information, how do you then get the information that is shown in Tableau Cloud for the Schedule Refresh information? I can see on the Cloud that for example I have a schedule like:

Every Mon, Tue, Wed, Thu, Fri, at 04:00 (UTC+01:00) GMT+01:00

N/A

8 Sept 2022, 04:07

9 Sept 2022, 04:00

The Last update I already have but I am trying to get the "Next update" scheduled and what the actual schedule is??

Thanks awefully,

Richard Browne
