You might notice that Data Studio is not provided as a stand alone integration block. Instead it's provided as an extension on some destination blocks.

Extensions are basically micro apps that depend on a specific block to work. Currently the Data Studio extension is available on the Google Sheets (destination) block. Once you add Google Sheets (destination) to your sketch you'll be able to see a button with the Google Data Studio Icon hovering under it. Click on it and select the sheet that you want to sync with your report and click build report to generate your report.
