How would I make this filtering enabled?

I have a gun that uses Raycasting but I'm not sure how to actually make it filtering. I've tried to but when I reference the Gun's handle in one of the arguments for FireServer() the output gave error that just said Handle is not a valid member of Player

Is there any other way I could make the gun tool filtering? Or is there any way to bypass this error.

If you would like to see my scripts, here is the script that is on the server-side.

local function GunRemoteFired(tool, Calcuation, Character)
	
	local ray = Ray.new(tool.BulletFire.CFrame.p, Calcuation)
	local part, position = game.Workspace:FindPartOnRay(ray, Character, false, true)
	
	local beam = Instance.new("Part", workspace)
	beam.BrickColor = BrickColor.new("New Yeller")
	beam.FormFactor = "Custom"
	beam.Material = "Neon"
	
	beam.Transparency = 0.25
	beam.Anchored = true
	beam.Locked = true
	beam.CanCollide = false
	
	local distance = (tool.BulletFire.CFrame.p - position).magnitude
	beam.Size = Vector3.new(0.3, 0.3, distance)
	beam.CFrame = CFrame.new(tool.BulletFire.CFrame.p, position) * CFrame.new(0, 0, -distance / 2)
	
	game:GetService("Debris"):AddItem(beam, 0.16)
	if part then
		local humanoid = part.Parent:FindFirstChild("Humanoid")
		local player
		if not humanoid then
			humanoid = part.Parent.Parent:FindFirstChild("Humanoid")
		end
		if humanoid then
			player = game.Players:GetPlayerFromCharacter(part.Parent)
			if player.Team == game.Teams.Zombies then
				humanoid:TakeDamage(35)
			end
		end
	end
end

Here is the cilent-side script.

local function Shoot()
	if debounce > 0 and IsActive and player.Character.Humanoid.Health > 0 and player.Team == game.Teams.Survivors then	
		RemoteEvent:FireServer(tool.Handle, (Mouse.Hit.p - tool.Handle.BulletFire.CFrame.p).unit * 300, player.Character)
		debounce = debounce - 1
		GunGUI.TextLabel.Text = preSetStringGuiText..debounce.." / "..maxAmmo
	elseif debounce == 0 then
		ReloadSound:Play()
		mouseEvent:Disconnect()
		ReloadAnimation:Play()
		GunGUI.TextLabel.Text = preSetStringGuiTextReload
		for i = 1, 3 do
			GunGUI.TextLabel.Text = GunGUI.TextLabel.Text.."."
			wait(reloadTime / 3)
		end
		mouseEvent = Mouse.Button1Down:Connect(Shoot)
		debounce = maxAmmo
		GunGUI.TextLabel.Text = preSetStringGuiText..debounce.." / "..maxAmmo
	end
end
--debounce is basically just a numbered value that resets if it is 0. 

Thanks for viewing this!
