powerbi-js-api

I have a powerbi report embedded to my webpage. What I need is to add an "export" button to my page and export the report to the PDF when the button is clicked. How can I achieve this? People online advises using report.print() or window.print() , but both did not work for me. var reportContainer = document.getElementById('reportContainer'); var report = powerbi.embed(reportContainer, config); var report2 = powerbi.get(reportContainer); console.log(report); --returns the report console.log(report2); --also returns the report report.print(); --nothing happens report2.print(); --nothing happens
