How do you find an AirTag on the web
How do you find an AirTag on the web using iCloud.com's FindMyiPhone (not the app?)
Solution 1:
AirTags can only be tracked with Find My app, either on an iPhone/iPad or Mac - but not on the web.
Instructions from Apple for locating and AirTag:
Open the Find My app, then tap the Items tab.
Choose the AirTag you want to locate in the Items list.

Solution 2:
You can't find it on the web using https://www.icloud.com/find.
It is only visible in the owner's iPhone via the Find My app. It works away from the owner's phone.
Basically, it updates its location every time the tag finds any iPhone around.
