I have a small AI chatbot that I programmed. I am trying to inject it onto a Sparkle page using an embed command. Inside the Embedded Content block, I put this code:
<iframe src="ace-chat.vercel.app" width="90%" height="400" name="Chat Widget"></iframe>
When I load the page in preview mode, nothing shows up. I tried this code on a flat HTML file and it was able to load the web app in the frame. What am I doing wrong in Sparkle?
