Don't see tier upgrade option in google ai studio

I’m elligible for tier upgrade according to google’s documentation but I don’t see an option for it. Please help?

Hi @James_Han,

Welcome to the Forum,

Generally after meeting the criteria, an “Upgrade” button should appear on your API key page : https://aistudio.google.com/app/apikey. If you believe there is an issue, please DM me your Project ID for further investigation.

Thank you!
