I have embedded a PowerBI visualization onto my website.
I'd like the viewer of my website to be able to download the data that's shown in the charts.
This is easily done in the Power BI software itself- I simply click on the ellipses in the upper right hand corner and select "Export data." However, I can't see the ellipses once I've embedded the visualization/dashboard onto my website.
Am I missing something?

You can check out this Power BI Embedded sample which has the export data option as default:
