To use the Google Maps element, you must have a valid Google API key on your website to enable the styling options provided by Google.
To get a Google API key, follow this article from the Google Maps documentation:
https://developers.google.com/maps/documentation/javascript/get-api-key
Make sure to enable the “Maps JavaScript API” for your account and API key.
Once you have the key, go to Theme Options > Settings > API Keys, paste your API key, and save the changes. After that, you’ll be able to use the Google Maps element with all available options.
