Send the name of the player who used the item in chat

[eternal geyser]

I need a script that expands world border after using item and tells in chat the name of a player that used it. I did the first part about border, but idk how to send name of player

ItemEvents.rightClicked('kubejs:border_star', event => {
  event.item.count--
  event.server.runCommand('worldborder add 5')
  event.server.runCommand('tellraw @a "§bГраница мира расширенна!§r"')
})

you can get player name by event.player.displayName or event.player.name
you can also use server.tell to replace server.runCommand("tellraw")
And there's built-in Text class which makes creating chat component a lot easier

ItemEvents.rightClicked('kubejs:border_star', event => {
    const {item, server, player} = event
    item.shrink(1)
    server.runCommand('worldborder add 5')
    server.tell("§bГраница мира расширенна!§r")
    server.tell(
        Text.of("...")
        .append(Text.green(player.name))
        .append(Text.of("..."))
    )
})
