Add style to wordpress plugin

Hi all.

I have such a problem.
I have a wordpress project where I have a few plugins that add menus to admin panel.
Now I want to add styles to that plugins.

in my plugin’s index.php file I write

function my_admin_theme_style() {
    wp_enqueue_style('my-admin-theme', plugins_url('style.css', __FILE__));
}
add_action('admin_enqueue_style', 'my_admin_theme_style');

But this adds style.css’s style on every admin-page, but I need to add only on that one menu page that this plugin creates.

How to do it?
Thanks.
