Add items to header cart

Hello,
Header cart is created from code:

function avia_woocommerce_cart_dropdown_modified() {
	
	global $woocommerce, $avia_config;
	$cart_subtotal = $woocommerce->cart->get_cart_subtotal();
	$link = function_exists( 'wc_get_cart_url' ) ? wc_get_cart_url() : $woocommerce->cart->get_cart_url();
	$id = "";
	$added = wc_get_notices('success');
	$trigger = !empty($added) ? "av-display-cart-on-load" : "";
	
	if(avia_get_option('cart_icon') == "always_display_menu")
	{
		$id = 'id="menu-item-shop"';
	}

	$output = "<ul {$id} class = 'menu-item cart_dropdown {$trigger}' data-success='".__('was added to the cart', 'avia_framework')."'>";
	//$output .= "<li>PHP/HTML CODE TO ADD ENFOLD SEARCH ICON</li>";
	//$output .= "<li>ADD WISHLIST ICON</li>";
	//$output .= "<li>ADD LOGIN ICON</li>";
	$output .= "<li class='cart_dropdown_first'>";
	$output .= "<a class='cart_dropdown_link' href='".$link."'><span ".av_icon_string('cart')."></span><span class='av-cart-counter'>0</span><span class='avia_hidden_link_text'>".__('Shopping Cart','avia_framework')."</span></a><!--<span class='cart_subtotal'>".$cart_subtotal."</span>-->";
	$output .= "<div class='dropdown_widget dropdown_widget_cart'><div class='avia-arrow'></div>";
	$output .= '<div class="widget_shopping_cart_content"></div>';
	$output .= "</div>";
	$output .= "</li></ul>";
	echo $output;
}

Now I want to add list items for search, wishlist, and login (look commented out code). While wishlist and login are simple because I can add simple links to the corresponding pages.
But how to create the correct Enfold search icon? What code do I need?

The final result should look: result
