Sharepoint 2013 Document Library start custom workflow after item is published

I have a document library that uses major and minor versioning in library settings. I want to start a custom SharePoint Designer 2013 workflow as soon as an item gets published, inside this library. Am using Sharepoint 2013 on premises. How can I achieve this? I cant find a way of starting the workflow on publish, it starts on the first save of the item, when the item is not even checked in.

Thank you in advance
