How do I make this sprint script compatible on mobile devices?

Hey everyone! This is my first question on this forum, so sorry if anything is wrong or in the wrong format.

So, I have this thing in my game which allows you to sprint with the press of the shift button. It also plays an different animation while running.

Heres the full script, being parented in StarterCharacterScripts

local UIS = game:GetService("UserInputService")
local Player = game.Players.LocalPlayer
local Character = Player.Character

UIS.InputBegan:connect(function(input)
    if input.KeyCode == Enum.KeyCode.LeftShift then
        Character.Humanoid.WalkSpeed = 35
        Character.Humanoid.JumpPower = 65
        local Anim = Instance.new("Animation")
        Anim.AnimationId = "rbxassetid://5686974800" 
        PlayAnim = Character.Humanoid:LoadAnimation(Anim)
        PlayAnim:Play()
    end
end)

UIS.InputEnded:connect(function(input)
    if input.KeyCode == Enum.KeyCode.LeftShift then
        Character.Humanoid.WalkSpeed = 16
        Character.Humanoid.JumpPower = 50
        PlayAnim:Stop()
    end
end)

Is there anyway I can program a mobile button to activate some variation of this script when being held down? If you need any more info to fix my problem, please ask!
