How to deal with "Unknown Apple Airtag detected" warning?

I recently switched from iPhone to Pixel 10, and I still have my iPhone as second phone. I have an Apple Airtag on my wallet, which connects to my iPhone.

My Pixel phone keeps warning me that there is an Unknown Apple Airtag. When I click the notification, it does not give me the options to allowlist this airtag to ignore this airtag.

It's quite annoying, since I know this is my airtag, but I don't want to disable the warning feature, just in case there is a real unknown airtag following me in the future.
