Different text for different order emails

Hello

How to insert different text on invoice depending on order email template (or by email status) with free plugin version if possible?
For example: put ‘text 1’ on the invoice if it’s Processing order email template, and put ‘text 2’ on the invoice if it’s a Cancelled order email template/status. Also to change the filename depending on these two.

I’ve tried something like

add_action( 'wpo_wcpdf_after_order_data', 'insert_text', 10, 2 );
function insert_text( $template_type, $order ) {
	if ( $order->get_status() == 'cancelled' && $template_type == 'invoice' ) {
		?>
		<p>text2</p>
		<?php
	}
}

but didn’t work
