The hook is applied in file wp-content\plugins\woocommerce-currency-switcher\views\shortcodes\woocs.php for the text manipulation in the switchers drop-down.
Example:
add_filter('woocs_currname_in_option', function($currency_name){ //return "Hello " . $currency_name . '!!'; return ""; });
Use it by your own logic.
