I'm looking for the code that sets the 'Everybody's calendars' boolean to false in the Calendar app so I can change it to true.  

I know altering the source code directly is not recommended practice and that I'll need to remember to change it again after every Odoo update, but I need everyone to be able to see all calendar events and I can't find any other way to change that default setting.  It's particularly important because on an iphone, the responsive calendar view does not display the tick boxes so users cannot change it manually. Requesting the desktop site on an iphone does not seem to work either.

It used to be in addons/calendar/static/src/js/ but I gather it's moved and I can't find it.
