How to view 2 collaboration view in 1 page?

I have a document, and I want to show 2 views in a page (in reactjs web), 1 view can annotate, scroll, and another view only can view.
However, collaboration session depends on users. In a page means login by one user, so how to create 2 views in a page, 1 view is for ‘leader’, 1 view is for ‘follower’?
