Custom Routes in NextJS to support countries and languages

My site paths are like –

• https://www.example.com/us/en/products
• https://www.example.com/us/es/products
• https://www.example.com/us/en/categories
• https://www.example.com/us/es/categories

or –

https://www.example.com/[countryCode]/[languageCode]/products

Though libraries like – next-intl provides a way to deal with languages only but not if it has some previous country code attached to it.

Let me know any pointer on this.
