Does anyone know the proper way to do this? Mousedown or key down for animation.

Okay so I'm sure you can tell by reading the code but if not I'm trying to play an animation when you press MouseButton1 or a certain key. I'm going to post all of the code I've tried and I would appreciate it some help correcting it. The first one is my most recent attempt which gave me an error of "UserInputService is not a valid member of InputObject" which I'm assuming means I can't use userinputservice for keydown. The only reason I'm using userinputservice is because this YouTube tutorial on how to do this wasn't working so I posted it and they suggested it. So I don't know maybe I'm doing all of this wrong.

--first way--
local UserInputService = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local function onInputBegan(input)
	if input.UserInputType == Enum.UserInputType.Keyboard then
		local keyPressed = input.KeyCode
	end 

local Animation = script:WaitForChild("Animation") 
	if input.UserInputService == "f" or "F" then
		Animation:Play()
		end 
end
UserInputService.InputBegan:connect(onInputBegan)
--second way--
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
game:GetService('UserInputService')
animation = script:WaitForChild("Animation")
enabled = false
mouse.Button1Down:connect(function()
	if enabled ==false
		enabled = true
		local animationTrack = player.Character.Humanoid:LoadAnimation(animation)
		animationTrack:Play()
		
		wait(3)
	end
end)
--3rd way--
local UserInputService = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
animation = script:WaitForChild("Animation")
enabled = true
	
local function onInputBegan(input)
	if input.UserInputType == Enum.UserInputType.MouseButton1 then
			repeat wait() until player.Character.Humanoid == player.Character.Humanoid:LoadAnimation(animation)

	end
end
UserInputService.InputBegan:connect(onInputBegan)
--4th way--
local UserInputService = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
animation = script:WaitForChild("Animation")
enabled = true

local function onInputBegan(input)
	if input.UserInputType == Enum.UserInputType.MouseButton1 then
			local animationTrack = player.Character.Humanoid:LoadAnimation(animation)
			animationTrack:Play()
			wait(1)
			enabled = true
			animationTrack:Play()
	end
end
UserInputService.InputBegan:connect(onInputBegan)

I can try to help you, but I'm REALLY tired so I can't really analyze your script. Anyhow, I can show you the proper way to do it.

-- Local Script Inside StartPack/StarterGui
local plr = game.Players.LocalPlayer
local char = plr.Character
local animation = char.Humanoid:LoadAnimation(script:FindFirstChild("Animation")) -- Change "Animation" to whatever the name of your animation is and make it a child to the script
game:GetService("UserInputService").InputBegan:connect(function(input) -- UIS 
	if input.KeyCode == Enum.KeyCode.Q then -- when q is pressed, do stuff. (change q to whatever key you want)
		animation:Play()
	end
end)

If you don't understand anything or it doesn't work, let me know.
