Native cordova calendar plugin

Hi there, i’m currently ask for help when trying to use the native calendar plugin. Some function call work but other simply does not giving any error or message, so it’s pretty hard to debug.

So the request for using the calendar of the device popup and everything is fine on this side, but when i try to fetch some event with .findEvent() or .findEventWithOptions(), no error, no message in return.

i can get .listCalendars() and .getCalendarOptions() data, maybe i have to switch to a particular calendar before make my calls ?

Thx in advance
