Pre-order bonus for Iceborne?

Just pre-ordered iceborne on here and was wondering if we would still be eligible for the pre-order bonus? Since it says that "Your order will be accessible as soon as the product has been released. You'll get a notification prior to release."
Will I be able to get the steam key when I get that notification prior to release? Or will it only send me the key on the day that the game launches, which would mean I wouldn't be able to add it to my account in time for the pre-order bonus right?
