How to Add Animated Elements in the Background Using D-ID Scenes API?

We are using the D-ID Scenes API to generate videos where an avatar speaks on a topic. To make the video more engaging, we want to display animated elements in the background, such as graphs, images, videos, or moving text, that dynamically enhance the explanation. However, we are facing challenges in integrating these animated elements. Could you guide us on how to achieve this within the D-ID Scenes API? Is there a way to overlay or synchronize animations in the background while the avatar is speaking?
