Custom Google maps with Webflow does not working on existing template

Hello! I am a newbie on Webflow. I was following the steps " Custom Google Maps with Webflow CMS Items" on YouTube. It worked on a new template as the video guided. I want to embed it on an existing template but no success when it published.

Where should be the map? Could you please share a screenshot.
