I need to export the built in SharePoint page analytics and build some reports in PowerBi from the data.

The graph API appears to provide some sharepoint data. e.g "getSharePointSiteUsageDetail"

but the exported data is very basic and high level. 

this is the output from 

getSharePointSiteUsageDetail

getSharePointSiteUsagePages;

these dont provide anywhere near the detail that the built in page analytics do. 

Is it possible to export the page analytics from Sharepoint?
