The Steam Gifts category does not show untradable gifts.
On how to send untradable gifts to the bot:
First of all, add the bot as friend via http://dispenser.tf/view_customization/ , under Invite Friend, put in your SteamID64, you should receive a friend invite.
The "Accept Game Gift" button is used after you sent gifts to the bot from your Steam account. It is to notify the bot to receive the gifts.
