Dear Aternos Team,
Can you please install the mod "Player Compass"?
Link to mod: https://www.curseforge.com/minecraft/mc-mods/player-compass
This mod is a compass that dynamically points towards a player's position. The user can right-click to change the person the compass is pointing towards. It is useful for quickly figuring out where a friend is if you are adventuring together and get split up. It can also be used for a manhunt in a modded world.
best regards,
