How do I make an afk system work with this script?

I tried making a text button that changed the humanoid root part name but that made it so u cant jump and animations are weird

If anyone knows a way to do this it will greatly be appreciated

Id just like a button that can remove a player from the teleport list

local ServerStorage = game:GetService("ServerStorage")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")

local Maps = ServerStorage:WaitForChild('Maps'):GetChildren()
local Status = ReplicatedStorage:WaitForChild('Status')

while true do
	
	--Intermission
	
	local Countdown = 15 -- ten second intermission, 
	
	repeat wait(1)
		Countdown = Countdown - 1
		
		Status.Value = 'Intermission : '..Countdown
	until Countdown <= 0
	
	--Choose the map.
	
	Status.Value = 'Choosing Map.'
	
	local ChosenMap = Maps[math.random(1, #Maps)]:Clone()
	local Spawns = ChosenMap:FindFirstChild('Spawns'):GetChildren()
	local RandomSpawn = Spawns[math.random(1, #Spawns)]
	
	wait(5) -- little pause,
	
	ChosenMap.Parent = workspace
	Status.Value = 'Chosen Map - '..ChosenMap.Name
	
	wait(2) -- little pause
	Status.Value = "Get Ready!"
	wait(2)
	Status.Value = "Teleporting Players"
	wait (1.5) 
	--teleport the players
	
	for _, Player in pairs(Players:GetChildren())do
		if Player.Character and Player.Character:FindFirstChild('Humanoid') then
			Player.Character.HumanoidRootPart.CFrame = RandomSpawn.CFrame
		end
	end
	Countdown = 2 -- Starting Round In, make this as long as you want
	
	repeat wait(1)
		Countdown = Countdown - 1
		
		Status.Value = "Round Started!"
	until Countdown <= 0
	
	Countdown = 58 -- Game Time
	
	repeat wait(1)
		Countdown = Countdown - 1
		
		Status.Value = 'Time: '..Countdown
	until Countdown <= 0
	
	--Kill the players
	
	for _, Player in pairs(Players:GetChildren())do
		if Player.Character and Player.Character:FindFirstChild('Humanoid') then
			Player.Character.Humanoid:TakeDamage(0)
		end
	end
	
	ChosenMap:Destroy()
	
	Status.Value = 'Round Ended! Waiting For New Game'
	
	wait(4) -- little pause
	
end
