How do i change teams using a key?

local UIS = game:GetService("UserInputService")
local plr = game.Players.LocalPlayer
local Debounce = true


local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local Teams = game:GetService("Teams")

UIS.InputBegan:Connect(function(Input)
	if Input.KeyCode == Enum.KeyCode.G and Debounce == true then
		Debounce = false
  wait(4)
player.TeamColor = BrickColor.new("Brick yellow") 
wait(1)
	Debounce = true
	end
end)

i tired this scirpt but when i hit G it doesnt put me in the team i want instead makes a new team called neutrals
