code and save browser interaction?

[orduek]

Hi,
I'm trying to implement the getinteraction data function in my experiment (running on cognition.run) to assess participants' attention and focus.
Ideally, I would like to code whether the user moved to a different window/tab/closed full screen (as suggested in [https://github.com//issues/495]).
I'm struggling as to how to actually implement it in the data per trial and would be happy to hear ideas.

Thanks!
