How to determine who is exporting data from a Power BI Report Server Report?

[vickyd]

Is there a way to identfy who is exporting data from a Power BI report using any logs? In SSRS the ExecutionLog table clearly showed this but Power BI Report Server logs don't seem to show anything useful. 

We don't want to disable ability to export but we don't want our users to use the reports/dashboards as a data dumping tool and prepare offline reports based on that given the whole idea of building the reports/dashboards was to avoid having different versions being created by different people. We therefore want to determine who is exporting often and reach out to such users to understand why they are exporting and provide a better online solution instead.
