If you want your custom interactive overlays (that you have designed in Composer) to be clickable, swipeable, etc. for your viewers, you need to add them to your website by using a Singular Embed Code.
Interactive overlays only work on websites. Every time someone opens up your webpage and tunes into your show, Singular overlays are being rendered on their computer, allowing them to interact. This is called client-side rendering.
If you're a developer, you can check out the Singular Overlay SDK for custom implementation.
