If you are unable to log in to Google via the GFX module and need to use a Google Spreadsheet with your graphics overlays, we have a workaround option detailed below.
In your Google Spreadsheet, navigate to File > Publish to the web.
Copy the URL of your sheet. In Studio, add a Google Spreadsheet and select Enter a public Google spreadsheet. Paste your sheet's URL in the field below. Your data will then populate on the right side.
