Is there any way to hide project settings panel in axshare prototype page?

I’m doing an online usability test using Axshare prototypes. But testees could mistakenly quickly tap and evoke project settings panel which I don’t want them to see.

I tried using plugin script to delete two divs (mHideSidebar, mobileControlFrameContainer), but both are outside iframe which can’t be controlled by plugin script inside.

Any suggestions for this issue? Thank you a lot!
