How can I find the last location of my AirPods?

Re: "How to find the last location from my AirPods "

See if Apple Support's online video below can help:

See: Find your lost AirPods with Find My - Apple Support

Eg: says:

If your AirPods are "Offline" or show "No location found"

If your AirPods are out of range or need to charge, you might see their last known location. You might also see "Offline" or "No location found." You might be able to get directions to their last known location — but you won't be able to play a sound or use Find Nearby.

If they come back online, you get a notification on your iPhone (or other Apple device that you use them with).
