How to guild share map device from the Mystery Box?

I just opened a bunch of Dawn of the Hunt Mystery Boxes, hoping to get the Djinn's Map Device for use in my guild, but I can't figure out how to do that.

The list at https://www.pathofexile.com/my-guild/poe2/guild-giftable-transactions doesn’t show any of the items I got from the Mystery Boxes.

Would really appreciate some help!
