How can I automatically refresh data in a .pbix file saved on the server?

Hi,

I built a PowerBI report that updates the data every month. The data is updated according to the schedule set in Manage/Schedules refresh. In browser it always shows current data. However, when I save the report file to disk locally and then open it in Power BI Desktop, I do not see the current data. The downloaded file contains only the data that was imported when it was saved to the Power BI Report Server.
I would like the downloaded file to contain current data.

In file I use Data Connectivity mode as Import, because some end users do not have access to the database.

Thanks in advance.
