How to make UserInputService usable for mobile players?

I am working on something and I know how to script simple ones and scripted a script you can slide for few seconds but a problem comes when I tried to make it usable for mobile players and it failed but how can I make it usable?

Code here to make it solve easier:

local UIS = game:GetService("UserInputService")
local Character = script.Parent

local Animation = Instance.new("Animation")
Animation.AnimationId = "rbxassetid://9331454676" -- This animation is not usable, skip that

local KeyBind = Enum.KeyCode.LeftControl
local WouldThisPlayerSlide = true
local Context = game:GetService("ContextActionService")

local function onSlide(input, sildeEvent)
    if sildeEvent then return end
    if not WouldThisPlayerSlide then return end

    if input.KeyCode == KeyBind then
        WouldThisPlayerSlide = false
        local PlayerAnim = Character:WaitForChild("Humanoid"):LoadAnimation(Animation)

        PlayerAnim:Play()
        local Silde = Instance.new("BodyVelocity")
        Silde.MaxForce = Vector3.new(1,0,1) * 30000
        Silde.Velocity = Character.HumanoidRootPart.CFrame.lookVector * 100
        Silde.Parent = Character.HumanoidRootPart

        for count = 1,8 do
            wait(0.1)
            Silde.Velocity *= 0.7
        end
        PlayerAnim:Stop()
        Silde:Destroy()
        wait(5)
        WouldThisPlayerSlide = true
    end
end

UIS.InputEnded:Connect(onSlide)

Context:BindAction("Slide", onSlide, true, KeyBind) -- This is problem here, officer.
Context:SetPosition("Slide", UDim2.new(1, -70, 0, 50))
Context:SetTitle("Slide", "Slide")
