Embedded Report API - setZoom

[bytesizetrainer]

Tried to use the Set Zoom API mentioned in the Embed Analytics Playground.

But returns an error saying that the setZoom is not a function.

I have Setup Zoom as a Button on my App. The button press triggers below code. What could I be missing.

$('#zoomBtn').click(function(){
 const report = powerbi.embeds[0];
 report.setZoom(0.25);
})
