Add message below shipping methods based on taxonomy terms in WooCommerce - wordpress

Question

I'd like to add a custom message below the available shipping methods in the cart, but only if ALL products in the cart have a tag named 'express'.
Therefore I use this snippet:
add_action( 'woocommerce_after_shipping_rate', 'action_after_shipping_rate', 20, 2 );
function action_after_shipping_rate ( $method, $index ) {
if( 'flat_rate:1' === $method->id ) {
echo __("<p>Arriving on your chosen date between 9am - 1pm Perfect for business addresses & special occasions</p>");
}
if( 'flat_rate:2' === $method->id ) {
echo __("<p>Arriving on your chosen date between 9am - 7pm Perfect for residential addresses</p>");
}
}
add_filter( 'woocommerce_shipping_details', 'hide_shipping_details', 10, 2 );
function hide_shipping_details( $rates, $package ) {
$terms = array( 'express' );
$taxonomy = 'product_tag';
$found = false;
foreach( $package['contents'] as $cart_item ) {
if ( !has_term( $terms, $taxonomy, $cart_item['product_id'] ) ){
$found = true;
break;
}
}
if ( $found === false ) {
remove_action( 'woocommerce_after_shipping_rate', 'action_after_shipping_rate', 20, 2 );
}
}
But right now, the custom message remains if 1 or 2 products have the tag 'express' but not ALL products. Can someone help me solve this problem?

No need to call from one hook to another, while you can just loop through all the products in cart in the woocommerce_after_shipping_rate hook
So you get:
function action_woocommerce_after_shipping_rate( $method, $index ) {
// Settings
$terms = array( 'express', 'tag-1' );
$taxonomy = 'product_tag';
// Initialize
$flag = false;
// Loop through cart items
foreach ( WC()->cart->get_cart() as $cart_item ) {
// Checks if the current product has NOT any of given terms
if ( ! has_term( $terms, $taxonomy, $cart_item['product_id'] ) ) {
$flag = true;
break;
}
}
// When false
if ( ! $flag ) {
// Compare
if ( $method->get_id() === 'flat_rate:1' ) {
$text = 'My text 1';
} elseif ( $method->get_id() === 'flat_rate:3' ) {
$text = 'My text 2';
} elseif ( $method->get_id() === 'local_pickup:1' ) {
$text = 'My text 3';
}
// When isset
if ( isset( $text ) ) {
// Output
echo '<p>' . sprintf( __( '%s', 'woocommerce' ), $text ) . '</p>';
}
}
}
add_action( 'woocommerce_after_shipping_rate', 'action_woocommerce_after_shipping_rate', 10, 2 );
