How to request access to gemini flash 2.0 experimental Audio API?

The docs mention an early access list for the experimental audio API. Where can i apply to this? Or is it country restricted? (im in Europe, Germany)

Why did the google team remove that feature when it was introduced at the beginng of the year. I know its experimental but its really beneficial. It would be sad to see if they remove the experimental image API as well

I wanna build a weekend project with it
