Humblebundle

A friend sent me a humblebundle gift and i claimed it (i put the email) forgeting that i already had it. So i want to give it away

My question is..
The humblebundles gifts are usually before you input the email (https://www.humblebundle.com/gift?key..), however i already claimed it to my email and now it directs me to the page where you click the steam icon and it auto claims it to your account (humblebundle.com/downloads?key=...) but i havent clicked it yet

Is it impossible to give it away now? or can i still make a giveaway at the redeeming part(humblebundle.com/downloads?key=..)
