如何给wordpress的编辑器添加一个自定义按钮，并且实现插入功能

add_action('media_buttons', 'add_my_media_button');

function add_my_media_button() {
    echo '<a href="#" id="insert-my-media" class="button">Add my media</a>';
}

function include_media_button_js_file() {
    wp_enqueue_script('media_button', 'path/to/media_button.js', array('jquery'), '1.0', true);
}

jQuery(function($) {
    jQuery(document).ready(function(){
            jQuery('#insert-my-media').click(open_media_window);
    });
    
    function open_media_window() {
        if (this.window === undefined) {
            this.window = wp.media({
                    title: 'Insert a media',
                    library: {type: 'image'},
                    multiple: false,
                    button: {text: 'Insert'}
                });
     
            var self = this; // Needed to retrieve our variable in the anonymous function below
            this.window.on('select', function() {
                    var first = self.window.state().get('selection').first().toJSON();
                    wp.media.editor.insert('[myshortcode id="' + first.id + '"]');
                });
        }
     
        this.window.open();
        return false;
    }
});
