Path of Exile 2 Early Access is not available in my region (Macao)

Hello,

I received an early access key from my brother who bought the game. I redeemed it on this website before the launch date.

Today, I was trying to redeem the steam key retrieved from here: https://www.pathofexile.com/my-account/early-access , but it showed this:



I tried to launch the game from the standalone launcher, but it prompted me for plain email+password login. The current account is created via Steam OAuth so it doesn't have email+password login.

Is there anyway to salvage this?
