This process is very simple, let’s do it together:
In the left side menu, look for the module called: Publish and click on it.
Inside this module in the top center you will find a button called: History. Click on it.
That’s it. In this window you will find the list of all the posts you have created. You will find published posts, pending posts and even draft posts.
Here you can also perform other actions such as duplicating the posts you have already created and at the top you can filter by date or by type of post if you wish.
