The instructions you pasted are for claiming a name that was pre-reserved when Handshake launched [1]. This is different from creating and obtaining a new name on the blockchain.
The popular names are in the names folder.
I wouldn't recommend obtaining a new name from any random website. I don't think I did so. I'm going to avoid continuing this thread as gaslighting isn't usually something one would wish to engage in, obviously on the receiving end, but on the creator's end too.
I hope you are able to find peace in the next year.
Happy new year to you.
