How to make tools without Tool.Activated work on mobile?

This is my first time using Scripting support, i apologize if there were a mistake.

I am still mediocre at scripting, sorry if i misunderstood some parts.

I wanted to make my tool work with mobile, but the tool doesn't work with OnActivated()

I used roblox Golden Steampunk as my tool template to make my tool.

i was making a bat tool that works similar as the 'be dead forever simulator' bat, where when you used it, you can't move but kills anything.

How will i make it so the tool works when you tap as mobile? My server script:

local Tool = script.Parent
local StartEvent = Tool:WaitForChild("Start")
local Remote = Tool:WaitForChild("Remote")
local Handle = Tool:WaitForChild("Handle")

local FriendlyFire = false

local char = Tool.Parent

local HitAble = false
local HitWindup = 3.15
local HitWindow = 0.75
local HitDamage = 500
local HitVictims = {}

local SwingAble = true
local SwingRestTime = 9.5

--returns the wielding player of this tool
function getPlayer()
    local char = Tool.Parent
    return game:GetService("Players"):GetPlayerFromCharacter(char)
end

--helpfully checks a table for a specific value
function contains(t, v)
    for _, val in pairs(t) do
        if val == v then
            return true
        end
    end
    return false
end

--tags a human for the ROBLOX KO system
function tagHuman(human)
    local tag = Instance.new("ObjectValue")
    tag.Value = getPlayer()
    tag.Name = "creator"
    tag.Parent = human
    game:GetService("Debris"):AddItem(tag)
end

--used by checkTeams
function sameTeam(otherHuman)
    local player = getPlayer()
    local otherPlayer = game:GetService("Players"):GetPlayerFromCharacter(otherHuman.Parent)
    if player and otherPlayer then
        if player == otherPlayer then
            return true
        end
        if otherPlayer.Neutral then
            return false
        end
        return player.TeamColor == otherPlayer.TeamColor
    end
    return false
end

--use this to determine if you want this human to be harmed or not, returns boolean
function checkTeams(otherHuman)
    return not (sameTeam(otherHuman) and not FriendlyFire)
end

function onTouched(part)
    if part:IsDescendantOf(Tool.Parent) then return end
    if not HitAble then return end

    if part.Parent and part.Parent:FindFirstChild("Humanoid") then
        local human = part.Parent.Humanoid

        if contains(HitVictims, human) then return end

        local root = part.Parent:FindFirstChild("HumanoidRootPart")
        if root and not root.Anchored then
            local myRoot = Tool.Parent:FindFirstChild("HumanoidRootPart")
            if myRoot and checkTeams(human) then
                local delta = root.CFrame.Position - myRoot.CFrame.Position -- make the enemy face me

                tagHuman(human)
                human:TakeDamage(HitDamage)
                root.CFrame = CFrame.new(root.Position, myRoot.Position)
                table.insert(HitVictims, human)

                tagHuman(human)
                human:TakeDamage(HitDamage)
                root.Anchored = false
                root.Massless = false
                table.insert(HitVictims, human)

                local bv = Instance.new("BodyVelocity", root)
                bv.maxForce = Vector3.new(1e9, 1e9, 1e9)
                bv.velocity = delta.Unit * 125
                game:GetService("Debris"):AddItem(bv, 0.1)

                -- sounds
                Handle.Homerun:Play() 
                Handle.Smack:Play()
                Handle.bawnk:Play()

                wait(4)

                Handle.Voiceline3:Play()
            end
        end
    end
end

local function onLeftDown(property)
    if not SwingAble then return end
    Tool.Parent:WaitForChild("HumanoidRootPart").Anchored = true
    Tool.Parent:WaitForChild("HumanoidRootPart").Massless = true

    SwingAble = false
    StartEvent:FireClient(getPlayer()) -- activates the camera script
    delay(SwingRestTime, function()
        SwingAble = true
    end)

    delay(HitWindup, function()
        HitAble = true
        Handle.Boom:Play()
        delay(HitWindow, function()
            HitAble = false

end

function onRemote(player, func, ...)
    if player ~= getPlayer() then return end

    if func == "LeftDown" then
        onLeftDown(...)
