Export filters not applied when exporting an embed report requested with filters in url

Hi there, 

I am embeding a PowerBi report in my application. During embedding I am passing the filter parameter in the embed url. Like this

https://app.powerbi.com/reportEmbed?reportId=xxxx&groupId=xxxx=2&config=xxxxx&filter=Employees/employee_id eq 201445.

After the report is embedded, I am changing the slicers to modify the data and capturing the state of the report using the bookMarkManager.capture() method in PowerBi JS client. Later I am using this state to export the report to PDF. The problem is I am trying to pass some more filters through the ReportLevelFilters property of the PowerBIReportExportConfiguration object. But the report filters I am sending while exporting are not applied on the exporte PDF. I could still see the data from the captured state only. Any idea why the export filters are not working? Is it due to using the filters in the embed url?

Please let me know what is happening and any way to make it work.

I also observed if we didn't pass the filters in the embed url, then the export filters are working. Any way to make both work?
