How to Disable Cash On delivery on applying coupons

I want to disable cash on delivery on applying the coupons. In the code below, I have to add the details of each coupon separately to make it work. Could somebody tell a way to modify this code so it may work on each discount coupon available on my website.

 add_filter( 'wc_smart_cod_available', 'cod_restrict_coupons' );

function cod_restrict_coupons( $is_cod_available ) {
	global $woocommerce;
	$applied_coupons = $woocommerce->cart->applied_coupons;
	
	// add the coupon codes you want
	// to restrict in this array

	$restricted_coupons = array(
		'myfirst',
		'online15',
		'prepaid10',
		'nicholassparks',
		'booker',
		'kidsbooks',
		'wintersale',
		'offer15'
		
	);
	
	if( array_intersect( $restricted_coupons, $applied_coupons ) ) {
		$is_cod_available = false;
	}
	
	return $is_cod_available;
	
}
