Change “email changed” notification recipient

Hey,

I want to change the default recipient for “email changed” notification from user to email. I have tried to add this code in my function.php but it doesn’t work.

/* Change mail 'email changed' notification recipient from user to admin */
add_filter( 'um_email_notifications', 'my_email_notifications', 10, 1 );
function my_email_notifications( $emails ) {
$emails['changedaccount_email'] = array(
					'key'           => 'changedaccount_email',
					'title'         => __( 'Account Updated Email','ultimate-member' ),
					'subject'       => '{first_name} {last_name} updated the email on {site_name}',
					'body'          => 'Hi,<br /><br />' .
					                   'User {first_name} {last_name} with login {username} recently updated the email to {email}.<br /><br />' .
					                   'Thanks,<br />' .
					                   '{site_name}',
					'description'   => __('Whether to send the user an email when he updated their account','ultimate-member'),
					'recipient'     => 'admin',
					'default_active'=> true
);

return $emails;
}
