JitsiMeetView on iOS

Hi,
I would like to know, how to modify JitsiMeetView on iOS so it can give some space on top of the screen (for dedicated logo/banner/etc). Changing the size of JitsiMeetView didn’t work (can’t be edited to make constraints). I tried to make new UIView as superview and put JitsiMeetView as subview (like in picture attached), but it crashed in build process with message :

Thread 1: Exception: “-[UIView setDelegate:]: unrecognized selector sent to instance 0x7fd14181dd10”

I’m using Xcode 11. Any hint how to implement that ?

Thanks in advance.
