How to hide ManageWP from Plugins list

Hi.

I am trying to hide ManageWP plugin from the plugins list in order for people not to delete it. All the other plugins are mostly working except for a few

function hide_plugins_digital() {
global $wp_list_table;
$hidearr = array
(
‘worker/index.php’,
‘wp-file-manager/index.php’,
‘wp-mail-smtp/wp_mail_smtp.php’,
‘wordpress-seo/wp-seo.php’);

$myplugins = $wp_list_table->items;
foreach ($myplugins as $key => $val) {
if (in_array($key,$hidearr)) {
unset($wp_list_table->items[$key]);
}
}
}

add_action(‘pre_current_active_plugins’, ‘hide_plugins_digital’);

Could you let me know what the problem here is please?
