How am I supposed to check when a console player enters & leaves a GUI element?

I have a shop that opens up a "tooltip" next to the mouse when entering on computer, here's the code.

plr = game.Players.LocalPlayer
ReplicatedStorage = game:GetService("ReplicatedStorage")
GameItems = ReplicatedStorage:WaitForChild("GameItems")
UI = script.Parent
TIP = UI.ShopTooltip

function addComas(str)
    local x = tostring(str)
    return #x % 3 == 0 and str:reverse():gsub("(%d%d%d)", "%1,"):reverse():sub(2) or x:reverse():gsub("(%d%d%d)", "%1,"):reverse()
end

for _,Element in pairs(UI.ShopFrame.Items:GetChildren()) do
    if Element:IsA("TextButton") then
        SelTool = GameItems:WaitForChild(Element.Item.Value)
        WPConfig = SelTool:FindFirstChild("WeaponConfig")
        local function ComputerEnter()
            TIP.ItemName.Text = Element.Item.Value
            TIP.ItemCost.Text = addComas(require(WPConfig).Cost) .. " G$"
            TIP.ItemInfo.Text = addComas(require(WPConfig).MinDamage) .. "-" .. addComas(require(WPConfig).MaxDamage) .. " DMG / CD: " .. addComas(require(WPConfig).Cooldown)
            TIP.Position = UDim2.new(0,plr:GetMouse().X+1,0,plr:GetMouse().Y+30)
            TIP.Visible = true
        end
        local function ComputerMoved()
            TIP.Position = UDim2.new(0,plr:GetMouse().X+1,0,plr:GetMouse().Y+30)
        end
        local function ComputerLeave()
            TIP.Visible = false
            TIP.ItemName.Text = tostring(nil)
            TIP.ItemCost.Text = tostring(nil)
            TIP.ItemInfo.Text = tostring(nil)
            TIP.Position = UDim2.new(0,0,0,0)
        end
        Element.MouseEnter:connect(ComputerEnter)
        Element.MouseMoved:connect(ComputerMoved)
        Element.MouseLeave:connect(ComputerLeave)
    end
end

My questions: What event do I use on console for entering and leaving a selection? How do I check which platform the client is running on?
