Issue in Video sdk Ui layout


I am implementing Zoom Video SDK UI toolkit in my project. I am facing issue in Join Session Design. When i am joining Session UI shows design in below 3 parts 1. Self View (join user view)
2. Other View ( Cover other users and shared screen )
3. button row ( Cover all functional buttons )

My issue is that for number 2 video section’s height is too big and we need to scroll up and down to see full section. How can we reduce this Section height? If we can handle it then provide proper solution or code block.
