Sorry that is NOT proof. That's reference. Ever notice not one single real product leak has emerged in over 2yrs of all these rumours ... just renderings and such?
Oh and for that 'official' video of Apple's youtube about airtags in iOS menu ... again that's SOFTWARE, from a beta that NEVER released no developer ever actually saw it deployed. THAT should tell you something. It's STILL NOT a 'PRODUCT' ... if anything U1 chip is the product and 'airtag' is a service brand that is probably dying (kept up only by fans and so called leakers) ... FindMy is the service.
Everytime I've posted the above everyone replies to software/code to be hardware (it's not hardware by any evidence anyone has shown YET)! They, like you point to this mythical OS leak from Apple supposedly with no real evidence Apple themselves truly leaked it. How many videos of iPadOS did we ALL see on this site just 6-12 months before it showing up on real iPad's and iOS?
iPadOS was shown by a few UI designers about 6mths before it really debuted and refined (Files, multi-tasking of apps, split screen). iOS was shown to minimized call notifications about 14mths before we finally got it and it looks identical to what we have now.AirTag's ... still a pipe dream that is to debut on the next event (all the time and for so long now) still nothing. it's been, what, 2yrs+ now?
Also where is the video on their channel? I think it was leaked by someone else and not Apple. I just searched - nothing. Do you have the historical record of it being on their channel? Does anyone?
