How to find AirTag from the “help a friend” via the iCloud login?

Trying to find my son’s AirTag he left at home, but he’s abroad.

AirTags show up separately under “items” in the regular app, his phone etc.. show up in the “help a friend “ iCloud version, but that version does not have an “items” tab, so I cannot find the AirTag using the find device feature.

any ideas how to find the AirTag? We know it’s here at home somewhere but I cannot locate it like I can my AirTags - my AirTags are easy to find, it points the arrow and let’s me home in on them easy, but can’t select his AirTag
