For the SEO purposes I need to set up English as default language -> mynextapp.com/ when user enters the website, he/she can choose between ENGLISH or FRENCH, if English is selected the url will change to mynextapp.com/en, if the French will be chosen -> mynextapp.com/fr

Currently I am using the build in option in Next - i18n:

i18n: {
    locales: ['en', 'fr'],
    defaultLocale: 'en',
},

But this allows me to have English only as a default path = mynextapp.com/

Language Switcher:

    
        Switch
    

Is there a way how to handle the same language under different urls? So that when you click on "en" in language switcher, the url path should be myapp.com/en.
