Generate pages for each language

[adiusz]

Hi.
It's not the issue but you encouraged to ask for help, so I'm posting this :)

I need to add translations for Gatsby page I wrote but I get stucked. I am using DatoCMS for this project.
I have a simple gatsby-node file, and couple of product records, which has 2 language versions. Here is the file:

What I need is simply generate 2 versions of each node - 1 without any suffix in URL (which is working fine with that piece of code) and 1 with /en/product/${productName} suffix. Can you help with that? I really can't figure this out.

Thanks in advance!
