Lost a gamertag 🥲

So I was playing on The Hive and I got a random invite (I'm assuming from a bot), and it took me to a random server. I was playing on survival for a bit but I had to leave. There was text that said "add ____(insert username here) to join back". I thought I added the user but apparently not :/

All I remember was the username was a small jumble of letters and it started with an N If anyone knows the user please lmk I was in the middle of smelting a stack of iron and I really don't want to lose it 😣
