How can I change the team of all the players in the server? [closed]

So in this script, what I'm trying to do is have all the players in the game go on the team "Players" as Intermission ends.

local roundLength = 180
local intermissionLength = 5
local InRound = game.ReplicatedStorage.InRound
local Status = game.ReplicatedStorage.Status
local Players = game:GetService("Players")
local Teams = game:GetService("Teams")
local teamPlaying = Teams.Playing
local teamSpectators = Teams.Spectating


local LobbySpawn = game.Workspace.LobbySpawn
local GameAreaSpawn = game.Workspace.GameAreaSpawn
local Part = workspace.LobbyFloor

InRound.Changed:Connect(function()
    wait(1)
    if InRound.Value == true then
        Part.CanCollide = false

        wait(2)
        Part.CanCollide = true

    else
        for _, player in pairs(game.Players:GetChildren()) do

            local char = player.Character
            char.HumanoidRootPart.CFrame = LobbySpawn.CFrame
        end
    end
end)



local function roundTimer()
    while wait() do
        for i = intermissionLength, 1, -1 do
            InRound.Value = false
            wait(1)
            Status.Value = "Intermission: ".. i .." seconds left!"
        end
        for i = roundLength, 1, -1 do
            InRound.Value = true
            wait(1)
            Status.Value = "Game: ".. i .." seconds left!"
            local function onPlayerDied(player, character)
                -- When someone dies, put them on the spectator team
                player.Team = teamSpectators
            end
        end
    end
end

spawn (roundTimer)

I attempted to try and put code on line 19 stating player.Team = teamPlaying but that did not work. To make the script work, the script above needs to be placed in ServerScriptService and a script called LocalScript that's in Starter Gui under a ScreenGui named Timer and beside text that's named TimerDisplay. Also need an int value called InRound in ReplicatedStorage and a String value named Status. The following is localscript

local Status = game.ReplicatedStorage.Status
local TimerDisplay = script.Parent.TimerDisplay

Status.Changed:Connect(function()
    TimerDisplay.Text = Status.Value
end)
