Heatmap doesn't work for my web site

Hi.
I’m using pages from builder inside my web application. However I could not see any heatmap data. I could not find any spec about it. Do I need some extra settings inside my app or inside builder?
Thanks

Hey @Jediinspace, thanks for reaching out! Our heatmap functionality starts with our Growth plans. If you’re currently subscribed to a Growth plan and not seeing the heatmap available on published pages, please message me with your Public API key (located here Builder.io: Drag and drop page builder and CMS), and I’ll take a look on my end!
