Sending a message in the item name above hotbar

[iKiltMyslef]

Looking to do something like this as a way to have, in effect, an action bar message that can be two lines. There's a few ways to go about doing this, but I would like to try to stay away from changing a held item's name and changing it back to its original name (which also wouldn't work if the player is holding nothing).

Below is what I've tried, and I'm getting a single error when attempting to run, even though the Skript loads fine without any issues.

import:
    # ProtocolLib
    com.comphenix.protocol.PacketType
    com.comphenix.protocol.ProtocolLibrary
    com.comphenix.protocol.events.PacketEvent
    com.comphenix.protocol.events.PacketContainer

    org.bukkit.entity.Player
    org.bukkit.inventory.ItemStack

    org.bukkit.scheduler.BukkitRunnable


preimport:
    me.desht.dhutils.ItemMessage


# Original Java source: https://www.spigotmc.org/threads/itemmessagereloaded-popup-message-packet.304903/#post-2919253
public skript class me.desht.dhutils.ItemMessage:
    public and static void send(Player player, String message):
        set {_slot} to {_player}.getInventory().getHeldItemSlot()
        set {_stack0} to {_player}.getInventory().getItem({_slot})
        set {_stack} to new ItemStack({_stack0}.getType(), {_stack0}.getAmount(), {_stack0}.getDurability())
        set {_meta} to Bukkit.getItemFactory().getItemMeta({_stack}.getType())

        # fool the client into thinking the item name has changed, so it actually (re)displays it
        set {_meta} to {_meta}.setDisplayName({_message})
        {_stack}.setItemMeta({_meta})
        set {_setSlot} to new PacketContainer(PacketType.Play.Server.SET_SLOT)
       
        # int field 0: window id (0 = player inventory)
        # int field 1: slot number (36 - 44 for player hotbar)
        {_setSlot}.getIntegers().write(0, 0).write(1, {_slot} + 36)
        {_setSlot}.getItemModifier().write(0, {_stack})
        ProtocolLibrary.getProtocolManager().sendServerPacket({_player}, {_setSlot})

on region enter:
    if "%event-region%" contains "myhome":
        new ItemMessage(player, "test")

Error:

[15:24:30 INFO]: [Skript] No matching static constructor: ItemMessage.<init> called with (KiltMyself (CraftPlayer), test (String))

Can anyone tell what I'm missing here or doing wrong that would be causing this error?
