Question about the additional key for Path of Exile 2

Hello, sorry for my english, I use a translator.

I had a question, after buying the game POE2 on steam, I did an “upgrade” by buying the “Thaumaturge of the Vaal Supporter Pack” on the website.

I received everything but I don't need the extra key and I don't have anyone to give it to.

I would like to know if it will ever be possible to convert it into points in the store ?

Thank you
