Can this only happen for lock screen note taking? Can you take notes at other
times?

[tbarzic, 2017/06/13 19:17:59]

Notes can be taken at other times (i.e. from unlocked user session), but this
launch will only be called for notes taken on the lock screen (i.e. this class
is used only for lock screen note taking).

   apps::LaunchPlatformAppWithAction(lock_screen_profile_, app,
                                     std::move(action_data), base::FilePath());
   return true;
 }

   if (extension->id() ==
       primary_profile_->GetPrefs()->GetString(prefs::kNoteTakingAppId)) {
     OnNoteTakingExtensionChanged();
