How would I make a fly button that's compatible with mobile

Hello, I am working on making my game mobile compatible! There is a fly feature that lets players press f to fly. Obviously mobile players dont have a f key and I have no idea how I would go about making it compatible! Here’s the code:

lplayer = game:GetService("Players").LocalPlayer
local Mouse = lplayer:GetMouse()
flying = false
local potato = 1
Mouse.KeyDown:connect(function(key)
    if key == "f" then
	if potato == 1 then
	    repeat wait() until lplayer and lplayer.Character and lplayer.Character:FindFirstChild('HumanoidRootPart') and lplayer.Character:FindFirstChild('Humanoid')
    repeat wait() until Mouse
    speedfly = script.SPEED.Value
   
    local T = lplayer.Character.HumanoidRootPart
    local CONTROL = {F = 0, B = 0, L = 0, R = 0}
    local lCONTROL = {F = 0, B = 0, L = 0, R = 0}
    local SPEED = script.SPEED.Value
   
    local function fly()
        flying = true
        local BG = Instance.new('BodyGyro', T)
        local BV = Instance.new('BodyVelocity', T)
        BG.P = 9e4
        BG.maxTorque = Vector3.new(9e9, 9e9, 9e9)
        BG.cframe = T.CFrame
        BV.velocity = Vector3.new(0, 0.1, 0)
        BV.maxForce = Vector3.new(9e9, 9e9, 9e9)
        spawn(function()
        repeat wait()
        lplayer.Character.Humanoid.PlatformStand = true
        if CONTROL.L + CONTROL.R ~= 0 or CONTROL.F + CONTROL.B ~= 0 then
        SPEED = 50
        elseif not (CONTROL.L + CONTROL.R ~= 0 or CONTROL.F + CONTROL.B ~= 0) and SPEED ~= 0 then
        SPEED = 0
        end
        if (CONTROL.L + CONTROL.R) ~= 0 or (CONTROL.F + CONTROL.B) ~= 0 then
        BV.velocity = ((workspace.CurrentCamera.CoordinateFrame.lookVector * (CONTROL.F + CONTROL.B)) + ((workspace.CurrentCamera.CoordinateFrame * CFrame.new(CONTROL.L + CONTROL.R, (CONTROL.F + CONTROL.B) * 0.2, 0).p) - workspace.CurrentCamera.CoordinateFrame.p)) * SPEED
        lCONTROL = {F = CONTROL.F, B = CONTROL.B, L = CONTROL.L, R = CONTROL.R}
        elseif (CONTROL.L + CONTROL.R) == 0 and (CONTROL.F + CONTROL.B) == 0 and SPEED ~= 0 then
        BV.velocity = ((workspace.CurrentCamera.CoordinateFrame.lookVector * (lCONTROL.F + lCONTROL.B)) + ((workspace.CurrentCamera.CoordinateFrame * CFrame.new(lCONTROL.L + lCONTROL.R, (lCONTROL.F + lCONTROL.B) * 0.2, 0).p) - workspace.CurrentCamera.CoordinateFrame.p)) * SPEED
        else
        BV.velocity = Vector3.new(0, 0.1, 0)
        end
        BG.cframe = workspace.CurrentCamera.CoordinateFrame
                until not flying
                CONTROL = {F = 0, B = 0, L = 0, R = 0}
                lCONTROL = {F = 0, B = 0, L = 0, R = 0}
                SPEED = 5
                BG:destroy()
                BV:destroy()
                lplayer.Character.Humanoid.PlatformStand = false
            end)
        end
    Mouse.KeyDown:connect(function(KEY)
        if KEY:lower() == 'w' then
            CONTROL.F = speedfly
        elseif KEY:lower() == 's' then
            CONTROL.B = -speedfly
        elseif KEY:lower() == 'a' then
            CONTROL.L = -speedfly
        elseif KEY:lower() == 'd' then
            CONTROL.R = speedfly
        end
    end)
    Mouse.KeyUp:connect(function(KEY)
        if KEY:lower() == 'w' then
            CONTROL.F = 0
        elseif KEY:lower() == 's' then
            CONTROL.B = 0
        elseif KEY:lower() == 'a' then
            CONTROL.L = 0
        elseif KEY:lower() == 'd' then
            CONTROL.R = 0
        end
    end)
potato = 0
    fly()
    else 
		flying = false
        lplayer.Character.Humanoid.PlatformStand = false
		potato = 1
		end end end)

Nothing special, thanks for reading!

Hd admin and Adonis are open sourced and both have a fly command.

they use chat command to use fly.
if you dont want chat, create a button on screen to activate fly.

Try using context action service it will create a button for mobile and works on pc.
