Unknown AirPods: View 'first seen' notification history?

my friend has had a pair of unknown AirPods showing up with her for a while now and today I got a similar notification as well. basically, I would like to know if it is possible to check the “first seen” time history and see when the first notification started for these AirPods (probably weeks or months at this point). And also if she has paused the tracking notifications for it (not sure if she did or not), if we unpause the notifications will it still show the previous and/or updated “unknown device” data? Also what if the device is added in Bluetooth now but we delete it back to unknown again? I think I may be close to finding out something but we need to compare data first and I would like to know how detailed this data really is or if someone knows how i could find this stuff out. Thank you in advance!
