How can I still find a AirPod when it’s dead

I lost my left AirPods on Sunday night but I didn’t realize it until Monday morning But when I try doing find my AirPods it says both of them are here but my left AirPod is probably dead or not there. When I try pressing the left button to hear the sound it won’t let me. I have try refreshing it and trying YouTube anything to figure out how to find the missing AirPod and I don’t have any luck so I’m not sure what to do
