Unknown “accessory“ in Bluetooth list

This is a repost of a question somebody asked a while back but it wouldn’t let me reply. I have a feeling the unknown “accessory“ in the Bluetooth list is referring to my AirTag on my dog. When the AirTag battery gets low, it has a mention of using Bluetooth to locate, for energy purposes. I’m hoping someone at Apple or a professional can verify my hypothesis. I noticed this soon after realizing my Dogs AirTag was low. I’ve also posted the photo of the original question, but I couldn’t reply and there wasn’t an answer that seemed reasonable. Thanks!
