How can I make a Teleportation script using a gui ?

The problem with my script its how can I Find A player when he joins without knowing his name so

script.Parent.MouseButton1Click:connect(function()
    local Player = ?
    if Player then
        local Torso = Player:FindFIrstChild("Torso")
        if Torso then
            Player.Torso.CFrame = CFrame.new(Vector3.new(-107, 0.6, 17))
        end
    end
end)
