How do I get the Reminders app to work?

I installed the Reminders app on Ubuntu Xenial (not Ubuntu Touch):

sudo apt install reminders-app

It doesn't seem to start correctly:

Running against the production server
using main qml file from: "/usr/share/reminders/qml/reminders.qml"
virtual void OnlineAccountsClient::Plugin::registerTypes(const char*) Ubuntu.OnlineAccounts.Client
file:///usr/share/reminders/qml/reminders.qml:312:23: Type NotesPage unavailable 
                     page: NotesPage { 
                           ^
file:///usr/share/reminders/qml/ui/NotesPage.qml:41:30: Type EditNotePage unavailable 
         bottomEdgePageComponent: EditNotePage { 
                                  ^
file:///usr/share/reminders/qml/ui/EditNotePage.qml:37:5: Type EditNoteView unavailable 
         EditNoteView { 
         ^
file:///usr/share/reminders/qml/ui/EditNoteView.qml:24:1: module "Ubuntu.Content" is not installed 
     import Ubuntu.Content 0.1 
     ^

How do I get it to start correctly? I think I am missing one of the qml-module-ubuntu-* packages but I don't know which one.
