How to add multiple sender email addresses in WordPress and WooCommerce?

I am trying to add multiple email addresses or change the email address where customer responses to order notifications are sent.

I have the WooCommerce configuration as follows:

WooCommerce => Settings => Emails => Email Sender Options => Sender Address:

Initially, in this configuration I had the following email: [email protected]

I have tried to add two different email addresses, separating them by a comma ("," ), as follows:

[email protected], [email protected],

But this doesn’t work.

When the user responds to the email that arrived to notify him that his order was received, his message is not sent and he receives the following notice:

Address not found
Your message has not been delivered to [email protected]
because the domain mybusiness.commyemailgmail.com was not found. Check that there are no typos or spaces required and try again.

This is displayed as you see it, the email addresses together.

I have asked professionals and they have suggested some function with php.
I have used some example but it doesn’t work either.

function custom_change_reply_to_address( $headers, $email_id, $order ) {
    // Verificar si el correo electrónico es para notificar al cliente sobre el pedido completado
    if ( $email_id === 'customer_completed_order' ) {
        // Cambiar las direcciones de correo a las que quieres que lleguen las respuestas del cliente
        $new_reply_to_emails = array(
            '[email protected]',
            '[email protected]',
            '[email protected]',
        );

        // Convertir el array de direcciones en una lista separada por comas
        $new_reply_to_email = implode( ',', $new_reply_to_emails );

        // Remover el "Reply-To" actual, si es que existe
        $headers = preg_replace( '/^Reply-To:/m', '', $headers );

        // Agregar la nueva lista de direcciones de correo al encabezado
        $headers .= "Reply-To: $new_reply_to_emailrn";
    }

    return $headers;
}
add_filter( 'woocommerce_email_headers', 'custom_change_reply_to_address', 10, 3 );

How can I add two email addresses to this WooCommerce setup?
