Polylang URL

Hello,
I have a question.

In polylang we use this URL model https://www.domain.com/en/about-en/

I just don’t like how the abbreviation of the language was added after about. It does this for all language mutations. For example, the Russian version is displayed like this – /ru/about-ru/

I would need the url to be /ru/about/ /en/about/. How do I achieve this?
The page is called “About” and in the default language it is displayed with the correct url.
