That's now... I will lose the use of this tool. I'm not maintainer of a popular repository and I won't pay 10$/month at this time.
I will take a look on other opensource solutions (harder to install)

It seems that I participate to enough of #OpenSource projects on GitHub, so I can use Copilot for free.
Nice!
