payment instructions in email

Hello, I found a way to add the payment instructions to my Woocommerce emails, I also found a way to add text to for example, only the new order email. I tried combining those 2 thing so the payment instructions only will be shown in the new order email, but I did not get it to work yet. Anybody know what to change?

———payment instructions in woocommerce email > functions.php ——
add_action( ‘woocommerce_email_before_order_table’, ‘add_order_email_instructions’, 10, 2 );

function add_order_email_instructions( $order, $sent_to_admin ) {

if ( ! $sent_to_admin ) {

if ( ‘paymentgateway1’ == $order->payment_method ) {
// note
echo ‘<p>Instructions: blabla bla blaa blaa blaa</p>’; }

elseif ( ‘paymentgateway2’ == $order->payment_method ) {
// note2
echo ‘<p>Instructions: blabla bla blaa blaa blaa</p>’; }
else {
// other methods (ie credit card)
echo ‘blablabla blaablaa </p>’;
}
}
}

/* add_action(‘woocommerce_email_header’, ‘add_css_to_email’, 20, 2);

function add_css_to_email($email_heading, $email) {

// Adds CSS to “new order” email only
if ( $email->id == ‘customer_processing_order’ ) {

echo ‘TESTTTTTT’;
}
}
