Fullscreen mode button Power BI Embedded on Wordpress

Hi team,

I could embed Power Bi on my blog in worpress throught a plugin. But I can't show dashboards in fullscreen (in public dashboard this is possible). So I want to put a button "fullscreen" below each report to generate this action. How can I do this? I know that I need to use java, but I don't know how to create a code and put this in my blog in wordpress..

Any idea...

Thanks for your help!
