ChatService:RegisterChatCallback(player.UserId, onPlayerInput)

-- Sample ChatService module (ChatService.lua)
local ChatService = {}

function ChatService:RegisterChatCallback(userId, callback)
-- Your implementation to register a chat callback for the player with userId
-- This function should call the provided callback when a player with the given userId sends a chat message
-- You'll need to implement a way to handle player chat input and call the callback accordingly
end

return ChatService end

If doesnt work try this -- Main Script
local ChatService = require(game.ServerScriptService.ChatService) -- Replace the path with the actual path to your ChatService module

local function onPlayerInput(userId, message)
-- Handle the player's chat input here
print("Received chat input from player with UserId:", userId)
print("Message:", message)
end

-- Example usage for a specific player (replace with the actual player's UserId)
local player = game.Players:GetPlayerByUserId(123456789)
if player then
ChatService:RegisterChatCallback(player.UserId, onPlayerInput)
end
