New method of finding Vape in SS?

[no_____]

Hello all,
I was recently watching a video by Headed, and he showed off a new method of screen sharing. He was able to see sites visited in chrome private tabs and see vape being opened. I am concerned by the ability to do such things. Is their a way that I can render this unsuccessful?

Thanks

He doesn't, it does not possible to see which websites you visited in private navigation. He visited the website with the normal mode.
