Do I need metal plates to mount a monitor arm on my Ikea Malm desk?

Hello, I have a 35 inches monitor which weights around 6.6kg (14.6 lbs) without the stand. And I bought this stand ( https://www.amazon.com/HUANUO-Single-Monitor-Mount-Stand/dp/B08CXG57ZX not really from that link, but it's exactly this monitor, arm same model number).

The base seems to be wide enough, isn't it?

I've seen people using dual monitor arms with probably over what my monitor weights on an Ikea Malm desk, I'm wondering if I should be safe or not. Also, do I buy 2 metal plates in case I need it? One on top and one on the bottom?
