Showing more than an author

Hello

I've installed the Co-Authors Plus plugin to ad more than an author to the posts following these instructions:

https://www.wpbeginner.com/plugins/allow-multiple-authors-to-be-associated-with-a-post-in-wordpress/

So far all had gone smoothly and now I can have more than an author. My question is pretty simple:

Where can I found the theme template plage o function that outputs the name so I can add the code to show all the authors?

Thanks!!
