How to register nav for translation via Polylang plugin in WP?

Question

WordPress

Hello, I installed the Polylang plugin to translate the site, everything works fine, but the menu is not translated, tell me how to add the ability to translate it through the plugin menu?
On the forum, I found a solution, only for an inline element, through a function and but I don’t understand how to access the menu through this, it’s weak in php, tell me if someone knows the answer
pll_register_string('social1', 'social2');<?php pll_e('social2'); ?>
