How to add HTML into admin bar?

I found this code regarding adding a menu to the admin bar.

add_action( 'admin_bar_menu', 'admin_bar_item', 500 );
function admin_bar_item ( WP_Admin_Bar $admin_bar ) {
    if ( ! current_user_can( 'manage_options' ) ) {
        return;
    }
    $admin_bar->add_menu( array(
        'id'    => 'menu-id',
        'parent' => null,
        'group'  => null,
        'title' => 'Menu Title', //you can use img tag with image link. it will show the image icon Instead of the title.
        'href'  => admin_url('admin.php?page=custom-page'),
        'meta' => [
            'title' => __( 'Menu Title', 'textdomain' ), //This title will show on hover
        ]
    ) );
}

I am making a simple plugin where I would like to add HTML in the admin bar in place of the menu as shown in the example above. Two simple inputs I need to be displayed in the admin bar to be precise.

Can someone tell me how this can be achieved?
