customizer fields translation

Tried this in functions.php and text translation in polylang but no changes in customizer content.

/* polylang translation */
if ( function_exists( 'pll_register_string' ) ) :
	    /**
	     * Register some string from the customizer option array to be translated with Polylang
	     */
	    function my_pll_register_string() {
                //got settings from options array
		global $customizer_option_array;
		
			foreach($customizer_option_array $option=>$value){
				//echo $option.'-'.$value ;
				pll_register_string( $option, $value, 'my-theme-options', true );
			}

	    }
	    add_action( 'after_setup_theme', 'my_pll_register_string' );
endif;

Even customizer home page settings not available with polylang active.
