See Players on Compass

This mod allows players to see other players—and the distance between them—directly on the compass.

A white player icon appears on the compass to indicate the position of nearby players, making it easier to locate and meet up with one another in the world.

You can customize the mod by editing the configuration file located at
mods/loshtbh_SeePlayersOnCompass/config.json. From there, you can enable or disable the mod and adjust the ChunkViewRadius. By default, this value is set to -1, which allows for unlimited viewing range.
