Giro Sagen goggles - how to change lens?

I got the Giro Sagen goggles from their official website. They come with a bonus lens. The one on the goggles is a S2 while the bonus is a S1.

Problem that I am facing is that I cannot find any instructions on how to change the lens. I've scoured the internet, so I am coming for your help.

This is my first pair of goggles, so even if it's an easy "how-to", trust me I've never had to do it.
I appreciate any help you can provide.
