Upgradeing my supporter pack

So I was gifted the game from a friend and got a key i redeemed on this page

Later on I bought an other supporter pack on this page for the 300 and gifted the key to a friend since i already have the game

When I go to the store now it say i can upgrade not just by a key... but dose that upgrade my key that I was gifted or the key i gave to my friend?

I ask is since i didn't see the upgrade until after i bought the extra key... and when i look at transactions i only see the key I gifted to my friend not the key I used myself that i got gifted... and the upgrade option is on my friends key in transactions...??

would be nice to know what happens before I buy an upgrade since I don't accidently want to upgrade some1 else's key....

And if the upgrade is for the key i gifted.. then how do I upgrade my own key??

imho supporter packs and keys that unlock early access for poe2 are separate things.

if you bought a supporter pack for your account that contains a key and you upgrade it, it upgrades your account.
