Best Ways to Manage 3 Langages on Same Website

Hi,

I've a fresh website in English/French/Spanish.

English is my main target, but I want to leverage my articles with French and Spanish translations to see if it's a good idea.

I'm gonna use Polylang on WP, so I've this structure:
- website.com
- website.com/fr/
- website.com/es/

Do I have to do something specific in GSC or anything else to declare the other langages? Or just add website.com in GSC and hreflang tags of Polylang will do the rest?

Because it's gonna be 150 new articles in 3 months (so 450 in total) and I don't want to confuse google.

Thanks.

Anyone idea guys?

It's a bit old and only theory. Also it's about expeding and not creating a new website with different langages in the same time
