Dune Embeds not working on Google Data Studio

Create a report in Google Data Studio. You'll need to add a data source so just connect any random Google Sheet. Now you can add URL embeds (next to "Add a control"). Insert one and you'll be given a place to add the "External Content URL", previously, should you paste a dune embed link there. It would show the chart, now it fails to load and does not show anything. The "External Content URL" section will be erased if you click elsewhere since nothing ever loaded.
