Det fungerar inte med familjedelning.
As Apple has explained, the only AirTag privilege afforded to people in an iCloud Family Sharing group is that they can silence the "AirTag Detected" safety alert that appears when an AirTag is traveling with them that is registered to someone else. (Likewise, the owner of the AirTag can disable the safety alerts to prevent someone else's iPhone from detecting it as unwanted tracking.)
But that's as far as the Family Sharing functionality goes. AirTags are only meant to be owned by one person, and it's not currently possible to share an AirTag's location with another family member using another Apple ID. It's likely that Apple has omitted this feature due to privacy concerns, so whether or not it intends to introduce it in the future via some other form of implementation remains to be seen.
