Extra access key if purchase Supporter Pack on Steam

Hi. I got the key for POE2 a while ago from a friend, now after that banger of the announcement I'm trying to get my other friend into playing POE2, and I wanted to gift them a key. I want to buy King of the Faridun Supporter Pack in steam (I have some money left on steam), but it's the difference in wording that stops me.

So, if I check Supporter pack description on the POE website and in Steam there is a slight difference in the early access line: on the website it says "Path of Exile 2 Early Access or Path of Exile 2 Key" and in steam it's "Path of Exile 2 Early Access". I have POE 2 activated in steam, and on the payment screen for supporter pack it says "If purchasing for yourself, you will not receive an extra copy of: Path of Exile 2".

My question is: how can I buy supporter Pack in steam and still get the key to gift to my friend?

Thanks
