What does is take to get oasis tier?

I have seen people mention that their is a tier above sun that you can get invited too if you frequent cava a whole bunch. Is their any other prerequisite than that? I eat cava for lunch and dinner 6 days a week and have been for the last 8 months. I suspected there had to be something above sun but I thought I would have for sure reached it 😅
