Power BI embedded - Export chart to JPEG

I have embedded couple of charts on my ASP.NET MVC application. "powerbi.embed" is actually creating an iframe and inside an iframe, it is showing all the charts (SVG commands). I have one button on the screen with "Export" label.

When a user clicks on button chart needs to be exported in JPEG.

As of now, there is no feature/functionality available which can export chart into JPG.

I found a way if I can get the content of the iframe and get into the SVG text, I can convert SVG into JPG and get to the solution.

Unfortunately, when I try to get the iframe content from my page, It is throwing "access denied" error.

How would I achieve this, Any Idea?
