Show only current flag and shows names and flags in submenu

Hi there!

In the mega menu using Polylang, I would like to know, how do I hide only the name of the current language on the display, showing only the flag, when the user is accessing, leaving only names and flags inside the submenu. I would like to leave it, as in the image link i sent…
Do you have a css code to make this change, have a plugin or re-edit php/java Polylang source code?
Why don’t you have this option in the language switcher?
