Email It In + woocommerce_email_attachments

Hello,
I’m using Email It In to store all invoices in the Google Drive. I noticed, that not only invoices are sent there. I also found out, that our Terms & Conditions are stored in Google Drive too for each order.

To add Terms and Condition as PDF into our email, I’m using this code:

add_filter( 'woocommerce_email_attachments', 'bbloomer_attach_pdf_to_emails', 10, 4 );
 
function bbloomer_attach_pdf_to_emails( $attachments, $email_id, $order, $email ) {
    $email_ids = array( 'new_order', 'customer_processing_order', 'customer_on_hold_order' );
    if ( in_array ( $email_id, $email_ids ) ) {
        $upload_dir = wp_upload_dir();
        $attachments[] = $upload_dir['basedir'] . "/name-of-the-file.pdf";
    }
    return $attachments;
}

What do I need to do to keep this file from being emailed into Email It In?

Thanks for your help.
