How to auto update PowerBI app reports fetching data from salesforce

Hi,

I  want to know how do I update reports in published PowerBi app or does it happen automatically?

I have created a report using Salesforce report as dataset. The report is not that complicated and not much happening onto it, just using PowerBI to embed SF report on a private webpage where users can download in excel.

Any help appriciated.

Thanks.
