Hi there,
I just finish my twitch extension but i can’t get rid of a little issue,
When twitch is not in fullscreen my extension show up on mouse enter and hide on mouse leave but i have no clue on how to do this in fullscreen mode 
i would like to hide my extension when twitch overlay hide or something like that,
If someone have idea of how to achieve this, it would be nice !!
Thx,
Best regards
