Description
The decrypted plist for an AirTag that has been shared with me is the following. This is incompatible with the current library due to not having a private key. Yes, I've tried using the peerTrustSharedSecret as the private key, it doesn't work as-is.
Seems like a good way to implement this would be to examine the traffic to Apple servers when examining the location of a shared AirTag via the FindMy application. It may use a different endpoint for an intermediary step between peerTrustSharedSecret and privateKey.
