Hi, add this function at the bottom of your functions.php file (use a child theme or it will be overwritten on next update):
function brand_compact_navigation() {
$brand_settings = wp_parse_args(
get_option( 'brand_settings', array() ),
brand_get_defaults()
);
$search_icon = 'enabled' === $brand_settings['nav_search'] ? '<a href="#" class="search-form-icon"><i class="fa fa-fw fa-search menu-search-form-icon"></i></a>' : '';
?>
<div class="compact-menu-icons">
<?php echo $search_icon; ?>
<a style="cursor:pointer;" id="mobile-menu-button"> Menu </a>
</div>
<?php
}
