How do I change player's animations?

I've done a Script in ServerScriptService containing the following code:

local Players = game:GetService("Players")
 
local function onCharacterAdded(character)
	local humanoid = character:WaitForChild("Humanoid")
 
	for _, playingTracks in pairs(humanoid:GetPlayingAnimationTracks()) do
		playingTracks:Stop(0)
	end
 
	local animateScript = character:WaitForChild("Animate")
 
	animateScript.idle.Animation1.AnimationId = "rbxassetid://5432167890"
	
	animateScript.walk.WalkAnim.AnimationId = "rbxassetid://1759277502"
	
	animateScript.jump.JumpAnim.AnimationId = "rbxassetid://1760393958"
	
	animateScript.fall.FallAnim.AnimationId = "rbxassetid://1760423961"
end
 
local function onPlayerAdded(player)
	if player.Character then
		onCharacterAdded(player.Character)
	end
	player.CharacterAdded:Connect(onCharacterAdded)
end
 
Players.PlayerAdded:Connect(onPlayerAdded)

They told me to put this script in another place and change the script, but what should I do?
