Attachment pane in the right Zotero 5 window

I am moving to Zotero from Sente 6 and used to have a pdf pane seen.
I understand that previous versions of Zotero had an option of opening a pdf pane in the right most window of the app (among Info/Notes/Tags/Related) and now it is gone.

Is there anyway to enable it?
