Is there a way to retrieve a player's name from their XUID?

Like some sort of XUID-to-gamertag translator. I am aware of Player->getXuid(), but what I need is basically the opposite - getting their name from their XUID. Any help?

 

I asked this in discord before, the answer was to make a foreach online player and then an if statement. I haven't tested it and not sure if this method would cause lag
I'm writing this on my phone so i can't write code
