Whitespace while Power BI embedding in an iFrame.

Hi community members,

I have published a Power BI report on app.powerbi.com.  I need to the title on the page as shown:

 

Then I published to use File>> Publish to Web>> Embed the report as iFrame



and then embed this report to SharePoint Online. But it showed a very big white space as shown:

I tried to use different sizes for iFrame

 a) <iframe width="800" height="600"
b) <iframe width="680" height="510"
c) <iframe width="933" height="700

but I could not able to reduce the size the whitespace on SharePoint Online.

Any suggestions, please?

Thanks in advance.
