Currently, all code is executed server-side (on a Node VM Module created on Worker Threads, using Hono+Websocket to provide the ability to run it in Minecraft), so it is not possible to run Turtle inside the screen. However, if there is a lot of desire for such functionality, it may be possible to use a VM (such as scratch-vm) within the browser to run the code.
