How would I change between a hipFire animation and a aiming animation

Help and Feedback Scripting Support

So I have this script

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local animator = humanoid:FindFirstChildOfClass("Animator")

local aimingAnim = Instance.new("Animation")
aimingAnim.AnimationId = "rbxassetid://94679025189997"

local aimingTrack = animator:LoadAnimation(aimingAnim)

local userInput = game:GetService("UserInputService")

-- Start animation when RMB is held
userInput.InputBegan:Connect(function(input, gameProcessed)
	if gameProcessed then return end
	if input.UserInputType == Enum.UserInputType.MouseButton2 then
		if not aimingTrack.IsPlaying then
			aimingTrack:Play()
			aimingTrack.Looped = true -- Ensures animation stays playing
		end
	end
end)

-- Stop animation when RMB is released
userInput.InputEnded:Connect(function(input, gameProcessed)
	if gameProcessed then return end
	if input.UserInputType == Enum.UserInputType.MouseButton2 then
		if aimingTrack.IsPlaying then
			aimingTrack:Stop()
		end
	end
end)

The script is written with AI so I would like to rewrite the entire thing
so right now It just switches to the hipfire animation while its aiming and I would like for it to have two different animations one with it firing normally and another animation playing while holding down mouse button 2
