How to add SOURCE and VIA to posts?

Hi. I’m using Newspaper 7 and can’t find the place to add SOURCE and VIA. Where are those settings located?

Thanks!

Sorry, I found the answer on my own. For anyone else interested:

In Posts > Add New, underneath the block where you write your post, there’s a space labeled “Post Settings.” (It might be closed; if so, there’s a drop-down menu. Go to the “General” tab, and the Source and Via options are there.
