showing only specific page when embedding multipage report

Hi,

   We have a multipage report published to PowerBI Premium work space (App Workspace).

We are using below code to embed the report into web application.

But pageName is set to specific page of the report and settings are set as below, it still shows the default page only. What could be wrong?

pageName: 'Page3',
settings: {
filterPaneEnabled: false,
navContentPaneEnabled: false 
} 

 This shows Page1 though we are forcing to show Page3. Page1 is our default page of the report.
