Streaming agent's workflow is a good suggestion! We actually already have this feature - if you click the chat bubble button at the top-right corner, just below “Preview,” you’ll be able to see it. That said, the UI definitely needs to improve. We will try to make the AI agent's workflow more visible in our next update.
I’m currently looking into the issue that’s causing it to get stuck. It should work if you would like to try another way: connect the film studio MCP to your codex and let codex call the film studio mcp to create a video for your product.
