How can I make this script loop as long as the mouse button is down?

This is a semi automatic gunfire script that works, however, I need to make it a fully automatic script, which means I need to loop it but I can't seem to figure out how to loop it correctly. What should I do to make it where the gunshots repeat until the mouse button is let up?

local MaxAmmo = 30
local Reloading = false
local player = game.Players.LocalPlayer
local Mouse = player:GetMouse()
local playerGui = player:WaitForChild("PlayerGui")
local TextLabel = playerGui:WaitForChild("AmmoDisplay"):FindFirstChild("AmmoText")
local Ammo = MaxAmmo


-- global reload function --
local function Reload()
	Reloading = true
	wait(1)
	Ammo = MaxAmmo
	Reloading = false
end


-- holding item, print equipped --
script.Parent.Equipped:Connect(function()
	print("G36 equipped")
end)


-- click to attack --
script.Parent.Activated:Connect(function()
	
	print("fired "..Ammo)
	
	if Ammo > 0 and not Reloading then
		Ammo -= 1
		print(Ammo)
		script.Parent.GunShot:Play()
		
		workspace.Camera.CFrame = workspace.Camera.CFrame * CFrame.Angles(0.03,0,0)
		wait()
		workspace.Camera.CFrame = workspace.Camera.CFrame * CFrame.Angles(-0.01,0,0)
		wait()
		
		if Mouse.Target.Parent:FindFirstChild("Humanoid") then
			script.Parent.DealDamage:FireServer(Mouse.Target.Parent, 26)
		end

	elseif Reloading == false then
		Reload()
		script.Parent.GunShot:Stop()
	end

	while wait() do
		TextLabel.Text = Ammo.."/"..MaxAmmo
	end
	
end)


-- R to reload --
local Input = game:GetService("UserInputService")
Input.InputBegan:Connect(function(Key)
		
	if Key.KeyCode == Enum.KeyCode.R and Reloading == false and Ammo ~= MaxAmmo then
		Reload()
	end
	
end)

-- deactivate detect --
script.Parent.Deactivated:Connect(function()
	print("Stopped Firing")
end)

Use Mouse when the Tool is equipped

local Mouse= game.Players.LocalPlayer:GetMouse()

local Equipped = false

Tool.Equipped:Connect(function()
	Equipped = true
end)

Tool.Unequipped:Connect(function()
	Equipped = false
end)

Mouse.Button1Down:Connect(function()
	-- Stuff
end)

Mouse.Button1Up:Connect(function()
	-- Stuff
end)

Or you can use UserInputService but you need to seperate it with other devices.

UserInputService.InputBegan:Connect(function(input, gameProcessed)
	if input.UserInputType == Enum.UserInputType.MouseButton1 then
		-- Stuff
	end
end)

UserInputService.InputEnded:Connect(function(input, gameProcessed)
	if input.UserInputType == Enum.UserInputType.MouseButton1 then
		-- Stuff
	end
end)

-- For mobile

UserInputService.InputInput:Connect(function(input, gameProcessed)
	if input.UserInputType == Enum.UserInputType.Touchthen
		-- Stuff
	end
end)


UserInputService.InputEnded:Connect(function(input, gameProcessed)
	if input.UserInputType == Enum.UserInputType.Touchthen
		-- Stuff
	end
end)

But make sure you use If statement to check if the tool is equipped. If it works tell me if not tell me.
