How to downgrade my expired Education plan to a Starter plan and unlock my files?

Hi Figma Team,

My Figma Education plan recently expired. Now, all the design files I created under that plan are locked, and I am unable to edit or export them.

I want to switch my account to the free Starter plan so I can access my work again. Could you please tell me when my account will automatically convert to the Starter plan, or how I can manually downgrade it right now to unlock my files?

Thank you for your help!
