How long is the Copilot wait?

I applied for the Copilot tech demo. How long do I have to wait?

Hi @d9oss, welcome to the GitHub Support Community! Due to Copilot still being a limited technical preview we aren’t able to give a timeline for when you will get access to the feature. It’s still under active development so the release schedule isn’t certain. If you’ve signed up for the preview you’ll get an email notification once your account has been approved for access, though I can’t say when that will be.

on what basis is it given out ?
