Last update new url setting

Hi, first of all thanks for the plugin!

In the changelog of the last update I read something about changing the url of the invoices, I suppose it was about the one that customers see when clicking on invoice button in their list of orders. It said that it would be changed in the plugin settings but I didn’t find anything there and searching in the documentation I didn’t find anything about this either.
Where can I find where the url is changed? or perhaps I did not understand well and you did not refer to this url:
wp-admin/admin-ajax.php?action=generate_wpo_wcpdf&document_type=invoice&order_ids=18927&access_key=f13d2d0277&my-account=true

Thank you!
