Hey @onioncong, thanks for the follow-up!
On Figma for Education organizations, seat type isn't something you can change from your own account. It's managed by your organization's admin (usually your teacher, or whoever manages your school or district's Figma account).
The best way to get this changed, ask your Figma organization admin to head to the Admin tab, open the People tab, find your name, and change your seat type from View to Dev or Full. Since Education organizations are free, there's no cost tied to this. It's simply about what seat your admin has assigned you.
If you're not sure who manages your account, your school or district's IT contact should be able to point you to the right person.
Once you're on a Dev or Full seat, you'll get the full Education-plan MCP allowance I mentioned earlier: up to 200 calls a day, with a 10-per-minute cap, instead of the 6-per-month limit that comes with a View seat.

Let me know how it goes!
