How can I make this animation on this tool a Click animation on a mouse?

So here is the script:

local animation = Instance.new("Animation")
animation.AnimationId = "https://www.roblox.com/Asset?ID=1438749801"

local trackanimation = nil
local playability = true
function playAnimation(AnimationSource)
    if playability == true then
        local plr = game.Players.LocalPlayer
        trackanimation = plr.Character.Humanoid:LoadAnimation(animation)
        
          trackanimation.KeyframeReached:connect(function()
            print ('Working')
        end)
        trackanimation:Play()
    end
end

local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
local waituntilback = script.Parent.Parent.Tool.Equipped:connect()
script.Parent.Parent.Tool.Equipped:connect(function()
    if not script.Parent.Parent.Tool.Equipped:connect() then
        playAnimation(waituntilback) else
        playAnimation()     
    end
end)

But how do I make it where it shows up in the game and How do I make it where it's only a Mouse click. This script only when you pull out the tool it starts the animation.
