Problems with simple gun on mobile (ignore thumbstick with guns)

I have a gun which similarly shoots like mm2’s gun. The problem with this gun is that it sometimes doesn’t shoot when you’re on mobile. Compared to mm2’s gun, it ignores the mobile user’s thumbstick.

Client Code:

UIS.TouchTapInWorld:Connect(function(position, processedByUI)
	local touchstickEnd = player.PlayerGui:WaitForChild("TouchGui"):WaitForChild("TouchControlFrame"):WaitForChild("DynamicThumbstickFrame"):WaitForChild("ThumbstickEnd")

	if math.abs((mouse.X - touchstickEnd.AbsolutePosition.X)) < 18 or math.abs((mouse.Y - touchstickEnd.AbsolutePosition.Y)) < 18 then
	else
		if cooldown then
			return
		end

		if processedByUI then
			return
		end

		if not equipped then
			return
		end

		gunFiredMobileEvent:FireServer(position, workspace.CurrentCamera:ViewportPointToRay(position.X, position.Y))
		handle.Shoot:Play()

		cooldown = true

		task.wait(.5)

		handle.Reload:Play()
		handle.Reload.Ended:Wait()

		cooldown = false
	end
end)

Server Code:

gunFiredMobileEvent.OnServerEvent:Connect(function(player, position, unitRay, mh)
	if player.Character.Humanoid.Health <= 0 then
		return
	end
	
	local origin = handle.Hole.Position
	local ray = Ray.new(unitRay.Origin, unitRay.Direction * 300)
	local hitPart, worldPosition = workspace:FindPartOnRay(ray)
	
	local intersection = hitPart and worldPosition
	local distance = (origin - intersection).Magnitude
	
	local bullet = objects.Bullet:Clone()
	bullet.Size = Vector3.new(.15, .15, distance)
	bullet.CFrame = CFrame.new(origin, intersection) * CFrame.new(0, 0, -distance / 2)
	bullet.Parent = workspace.Bullets
	
	handle.Shoot:Play()

	coroutine.wrap(function()
		task.wait(.5)

		handle.Reload:Play()
	end)()
	
	if hitPart then
		local humanoid = hitPart.Parent:FindFirstChild("Humanoid") or hitPart.Parent.Parent:FindFirstChild("Humanoid")
		local hrp = hitPart.Parent:FindFirstChild("HumanoidRootPart") or hitPart.Parent.Parent:FindFirstChild("HumanoidRootPart")

		if humanoid and humanoid ~= player.Character.Humanoid and humanoid.Health > 0 then
			for i, particle in pairs(confetti:GetChildren()) do
				if particle:IsA("ParticleEmitter") then
					local newParticle = particle:Clone()
					newParticle.Parent = hrp
					newParticle:Emit(45)
				end
			end
			
			humanoid.Health -= 110
			handle.Hit:Play()
		end
	end
	
	ts:Create(bullet, TweenInfo.new(.4), {Transparency = 1}):Play()
	debris:AddItem(bullet, .41)
end)

I’ve spent days researching on how to ignore the thumbstick when using a gun on mobile. The code above is what I’ve gained from the researching.
