WP admin Translation only

Hello,

For my next project, I would like to have the authenticatd users get the ability to switch only the admin language (betwenn french and english for the moment). Polylang do this by default by adding a select dropdown menu in their profile. I don’t know if it is a good idea to inatall polylang only for admin language switching purposes, but this is the way I would like this feature to add…

Thanks in advance.
