Pet Tracker

I've had problems in the past of losing pets. One of which was an Allay. Man was incredibly helpful in my tree farm. I went inside my house to sleep (He follow me inside) and when I went to let him out the next morning he was.. gone. He didn't die, but he just kind of despawned or something even with his name tag. But I figured it could be similar to the banner function where if you look at a map, you can always know where that pet is, and their icon will appear on the side of the map if their position is known but just not on the specific map I have like how it works with multiple players if that makes sense
