I know a lot of people no longer use FB but I want to see if I can use it the same as on my pc.

I have the app open and on the news IMG_20200727_124753590.jpgfeed option. I can see all the posts that have been added but what I can't see is the list of people I have recently messaged/added etc on the right hand side.
Is it possible to add the names or not.
Thanks in advance
