hi ailyroot,

no time to sort out what you need, but see here 3 snippets using different wya to add such item to a theme main menu or custom menu, with fixed or free position… Test and take the one you need.

//fixed position
function my_nav_menu_notif_counter($menu) {      
        if (!is_user_logged_in())
                return $menu;
        else
                $notif = '<li>Notif '. bp_notifications_get_unread_notification_count( bp_loggedin_user_id() ) .'</li>';
                $menu = $menu . $notif;
                return $menu;
}
add_filter( 'wp_nav_menu_items', 'my_nav_menu_notif_counter' );

//choose position
function my_nav_menu_positioned_notif_counter( $items, $args ) 
{
    if( $args->theme_location == 'primary' ) // only for primary menu
    {
        $items_array = array();
        while ( false !== ( $item_pos = strpos ( $items, '<li', 3) ) )
        {
            $items_array[] = substr($items, 0, $item_pos);
            $items = substr($items, $item_pos);
        }
        $items_array[] = $items;
        array_splice($items_array, 0, 0, '<li>Notif '. bp_notifications_get_unread_notification_count( bp_loggedin_user_id() ) .'</li>'); // 0,0 is first position, 1,0 is second, etc

        $items = implode('', $items_array);
    }
    return $items;
}
add_filter('wp_nav_menu_items','my_nav_menu_positioned_notif_counter', 10, 2);

// depending the theme, $theme_location may vary and this one use a menu ID
function my_notif_link( $items, $args ) {

$theme_location = 'primary';// Theme Location slug
$existing_menu_item_db_id = 6; // menu id
$new_menu_item_db_id = 66; // unique id number
$label = 'Notificationas '. bp_notifications_get_unread_notification_count( bp_loggedin_user_id() );
$url = bp_core_get_user_domain(bp_loggedin_user_id()) .'notifications/';
 
if ( $theme_location !== $args->theme_location ) {
	return $items;
}
$new_links = array();

if ( is_user_logged_in() ) {
	  
	// only if user is logged-in, do sub-menu link
	$item = array(
		'title'            => $label,
		'menu_item_parent' => $existing_menu_item_db_id,
		'ID'               => 'fugit', // menu name
		'db_id'            => $new_menu_item_db_id,
		'url'              => $url,
		'classes'          => array( 'menu-item' )
	);

	$new_links[] = (object) $item;  // Add the new menu item to our array
	unset( $item ); // in case we add more items below

	$index = count( $items );  // integer, the order number.

// Insert the new links at the appropriate place.
	array_splice( $items, $index, 0, $new_links ); // 0,0 is first position, 1,0 is second, etc

}

return $items;
}
add_filter( 'wp_nav_menu_objects', 'my_notif_link', 10, 2 );

Happy testing 😉
