I understand that if I want to change the text before the author, within the blog, I have to use a filter. But where do add this filter? In a function file? (I’m having a child theme, but not really using it, acutally not using it at all) or Using Code Snippets like in https://docs.generatepress.com/article/adding-php/ ?
Besides, I really don’t know how to write this :
Instead of having $date par $author
I wish to have $date – $author
