Default language no added in url

[gvestit]

Hi,

I hope this message finds you well. We are currently looking to implement a specific URL architecture for our multilingual website and would like some guidance on achieving the desired structure.

Our website's default language is Spanish, and we intend to maintain Spanish URLs without any language path prefix. However, for English and French, we would like to append the language code to the URL. Below are examples of how we envision the URL structure:

Default Spanish Language URLs:

site.net (Homepage in Spanish)
site.net/nosotros (About Us page in Spanish)
English Language URLs:

site.net/en (Homepage in English)
site.net/en/about (About Us page in English)
French Language URLs:

site.net/fr (Homepage in French)
site.net/fr/nous (About Us page in French)
The main objective is to have the default language (Spanish) displayed as if it's a monolingual site (without language prefix in the URL), while the English and French versions would include the /en/ or /fr/ prefix respectively.

We would greatly appreciate any insights or recommendations on how to configure our routing module to support this URL structure. If there's any documentation or examples that you could point us towards, that would also be immensely helpful.

Thank you
