Has anyone used Copilot for Xcode?

I'm trying to get Copilot for Xcode https://github.com/intitni/CopilotForXcode running in Xcode. It's all installed as per the instructions, yet when I try to use it, it complains about a missing API key.

I've obtained a new API key from openai as instructed but I do not know how to get it into Copilot for Xcode. Any clues, anyone?

I should point out that I have an existing subscription from Github Copilot which I use in Cursor, a rather neat VS Code clone!

Copilot for Excode –> Service -> Chat Models -> Add Model Press the key icon and add your API key.
