KGear Security Lock Bracket for Apple MacBook Pro 13" (2020) & 16" Models

Will this work with the new mbp 14" models?

Does this work with the 2020 MacBook Air 13”?

Do you have to remove the old rubber pads on a Macbook Pro to attach this or does it fit over top of the old ones?

What is the size of the pad (looking like apple) of the security device and how does it get secured to the tablet or phone?
