Magento 2: Add custom tab to order details page in customer account

When a customer clicks on an order on his order history page he is then redirected to the order details page. In Magento 2 standard community edition there is just one tab that list a order summary with all ordered articles. I want to add a custom tab next to the Ordered articles tab the tab might be labled slightly different, I use another language. How can I do that Please notice, I do not want to add a tab to the customer account navigation on the left nor do I want to add a tab to the admin backend. I know that there are plenty of tutorials. This hint is just to avoid misunderstandings.
