How do you create a basic Wordpress admin pointer? in WordPress

Pointers in WP need 3 components:

1: wp-pointer css file

2: wp-pointer JS file

3: A JavaScript snippet

To 1 and 2

include them simply with:

wp_enqueue_style( 'wp-pointer' );

and

wp_enqueue_script( 'wp-pointer' );

The JS code:

    <script type="text/javascript">
    (function($){
        var options = {"content":"<h3>Personal Data and Privacy</h3><h4>Personal Data Export and Erasure</h4><p>New <strong>Tools</strong> have been added to help you with personal data export and erasure requests.</p><h4>Privacy Policy</h4><p>Create or select your site&#8217;s privacy policy page under <strong>Settings &gt; Privacy</strong> to keep your users informed and aware.</p>","position":{"edge":"left","align":"bottom"},"pointerClass":"wp-pointer arrow-bottom","pointerWidth":420}, setup;

        if ( ! options )
            return;

        options = $.extend( options, {
            close: function() {
                $.post( ajaxurl, {
                    pointer: 'wp500_isrc_pointer',
                    action: 'dismiss-wp-pointer'
                });
            }
        });

        setup = function() {
            $('#menu-settings').first().pointer( options ).pointer('open');
        };

        if ( options.position && options.position.defer_loading )
            $(window).bind( 'load.wp-pointers', setup );
        else
            $(document).ready( setup );

    })( jQuery );
    </script>

Of Course you need to wrap all them in a php file to check the user capabilities and check the dismiss from the users meta.

I have copied the WP pointer class in wp-admin/includes/class-wp-internal-pointers and made a custom one from it.

Here the complete code which i can call it with an action hook like:

add_action( 'admin_enqueue_scripts', array( 'isrc_Internal_Pointers', 'enqueue_scripts') );
add_action( 'user_register',array( 'isrc_Internal_Pointers', 'dismiss_pointers_for_new_users' ) );

The Full PHP file (include it in your code and call the 2 actions):

<?php
/**
 * Administration API: WP_Internal_Pointers class
 *
 * @package WordPress
 * @subpackage Administration
 * @since 4.4.0
 */

/**
 * Core class used to implement an internal admin pointers API.
 *
 * @since 3.3.0
 */
final class isrc_Internal_Pointers {

    /**
     * Initializes the new feature pointers.
     *
     * @since 3.3.0
     *
     * All pointers can be disabled using the following:
     *     remove_action( 'admin_enqueue_scripts', array( 'WP_Internal_Pointers', 'enqueue_scripts' ) );
     *
     * Individual pointers (e.g. wp390_widgets) can be disabled using the following:
     *     remove_action( 'admin_print_footer_scripts', array( 'WP_Internal_Pointers', 'pointer_wp390_widgets' ) );
     *
     * @static
     *
     * @param string $hook_suffix The current admin page.
     */
    public static function enqueue_scripts( $hook_suffix ) {
        /*
