"OnServerInvoke is a callback member of RemoteFunction" error? [Question solved]

I'm making a custom chat system that uses RemoteFunctions to give a chat handler script the required values to send a chatted message, through a custom GUI, and a RemoteEvent to send the message to all players in the game. I started building it yesterday, and overall it looks good. But I get an error while connecting an event listener to the remote function saying OnServerInvoke is a callback member of RemoteFunction; you can only set the callback value, get is not available.

I'll provide full code snippets of everything used for this. A good and reasonable answer would be perfect and well appreciated. Thanks.

P.S. I know that my chat script isn't fully complete. I'm just showing you how I'm trying to send arguements to a RemoteFunction.

Local chat script (ScreenGui):

01local uis = game:GetService("UserInputService")
02local plr = game.Players.LocalPlayer
03local chatEvent = game.Workspace.SendMessage
04local sendChatInfo = game.Workspace.ChatInvoker
05local chatting = false
06local chatserv = game:GetService("Chat")
07uis.InputBegan:Connect(function(input)
08    if input.InputType == Enum.UserInputType.Keyboard then
09        if input.KeyCode == Enum.KeyCode.Slash then
10            if not chatting then
11                chatting = true
12                script.Parent:CaptureFocus()
13            end
14        else if input.KeyCode == Enum.KeyCode.Return then
15            if chatting then
16                chatting = false
17                local msg = script.Parent.Text
18                sendChatInfo:InvokeServer(plr, msg)
19                script.Parent:ReleaseFocus()
20            end
21        end
22        end
23    end
24end)

Custom Chat Handler (global script):

1local SendMessageEvent = game.Workspace.SendMessage
2local ChatInvoker = game.Workspace.ChatInvoker
3ChatInvoker.OnServerInvoke:Connect(function(plr, msg)
4    game.Chat:FilterStringAsync(msg)
5    SendMessageEvent:FireAllClients(plr, msg)
6end)

Remember; the error is coming from the chat handler that tries to add an event listener to a RemoteFunction at line 3 of the chat handler. There's nothing else conflicting.

Any assistance to help me build an accurate custom chat system is also acceptable.

remote events and functions

since you dont seem to know the difference between and remote function and event im gonna explain the general idea. RemoteFunctions are for returning a value such as string, int, boolean values etc. RemoteEvents are for communicating to the client or server to do a task which the side the caller or invoker is on cannot do.

1--firing and invoking the server
2 
3RemoteEvent:FireServer()
4 
5print(RemoteFunction:InvokeServer()) -- prints "hello"

then listen for them

1--listening 
2 
3RemoteEvent.OnServerEvent:Connect(function(player)
4    print("hello") -- prints "hello"
5end)
6 
7RemoteFunction.OnServerInvoke = function(player)
8    return "hello" -- returns the string value "hello"
9end
