Google Classroom Add freezes website

I am just using the free version and don’t want the google Classroom integration (yet). I deployed the extension and now Post to Kami is listed in all the teachers Classroom Classes.

  1. Can that option be removed globally?
  2. (bug) If a teacher does clicks the Kami assignment it brings up the pop window, and when that pop up is closed it brings up an add. When the add shows the mouse click no longer works on the page (except for on the add), and I am unable to click the x to close the add either. The only way to get back to classroom is by refreshing the page.
