I am trying to add a player to a chat channel if they have a tool equipped, so for i have the following script. There is already a chat channel created and i can join it manually by typing /j Radio in the main chat window. When i equip the tool the script just prints equipped in the output window.

local ServerScriptService = game:GetService("ServerScriptService")
local ChatService = require(game:GetService("ServerScriptService"):WaitForChild("ChatServiceRunner"):WaitForChild("ChatService")) 
local Tool = script.Parent


function Equip()
    print("equipped")

    ChatService.SpeakerAdded:Connect(function(PlayerName)
        print(PlayerName)
        local Player = game.Players:FindFirstChild(PlayerName)
        if Player and Player:GetRankInGroup(8370936) >= 190 then 
            print("Join the channel!")
            local Speaker = ChatService:GetSpeaker(PlayerName)
            Speaker:JoinChannel("Radio")
        end
    end)
end

function Unequip(mouse)
    print(" not equipped")
end

Tool.Equipped:connect(Equip)
Tool.Unequipped:connect(Unequip)

Please do not ask people to write entire scripts or design entire systems for you. If you can’t answer the three questions above, you should probably pick a different category.
