I already created new custom tab using this tutorial: https://magenticians.com/add-custom-tab-magento-2/
But it is located on left side. I need to place it at end (right side) like it is on this picture: https://i.stack.imgur.com/Stqen.png
I should be using move element like it is mentioned in this manual: http://devdocs.magento.com/guides/v2.0/frontend-dev-guide/layouts/xml-instructions.html
But I don't know how to do this.
Please help me.
