>Github Copilot is just a front-end

Yes, Copilot is often used to refer to both frontend and backend.

Also, the chatbot aka Copilot must have features on its own. Like I say to Roo Code/Cline on VSCode: Write a python script to output hello world.

And they will do exactly that, Roo Code is pretty impressive. Copilot on its own is dogshit and when using it the same way I would use Perplexity AI or ChatGPT, it is twice as much dogshit.
