Meteor.publish on server doesn't show new documents on client

Question

The problem is the next code on server:

Meteor.publish(null , function() {
    let events = [];
    Groups.find({participants: this.userId}).forEach(function(item) {
        events.push(item.latestEvent);
    });
    return Events.find({_id: {$in: events}});
});

doesn't provide possibility to see new documents on the client > Events.find().fetch() without reloading the page.

Both collection are in the lib folder:

Groups = new Mongo.Collection('groups');
Events = new Mongo.Collection('events');

I'm pretty sure the issue is in reactive source of data, but still cannot fix it.

Thank You for help!

Yes, you are right: only Events collection is reactive. There is simple way to solve it by using publish-composite package:

Meteor.publishComposite(null, {
    find(){
      return Groups.find({participants: this.userId});
    },
    children: [{
      find(group){
         return Events.find({_id: {$in: group.latestEvent}});
      }
    }]
});

But this solution has one disadvantage: Groups documents are published as well. So, probably you should exclude some fields from it.
