Correct way to close dirrect sessions

[airstep]

Below this:

Streamy.sessionsForUsers(uid)

This method behaves similarly to sessions, however it looks up the sessions based on user id(s). It returns a special object which contains one method: emit which works the same as the core#emit method.

I have a question: What is the correct way to close returned this 'special object'? Just assigned to 'null' after end of use it? But in such way it doesn't work.... after I close window and has on detach this lines:

`
Streamy.off(this.selectedChat._id);
Streamy.close()

if (this.streamy)
  this.streamy = null

`

I still get events in DEBUG console like this:

Object {senderId: "Yy9jfaxxtLcHWeQvS", status: "", __from: "4MgyX38TroGc7c3TL", msg: "streamy$mPqyC2Yv7jbPN5CG9"}

And in the beginning:

`
refreshStreamy() {
Streamy.off(this.selectedChat._id)

Streamy.onConnect(() => {
  console.log('streamy connected!');
})

Streamy.onDisconnect(() => {
  console.log('streamy disconnected!');
})

let userIdList = this.selectedChat.memberIds.filter(id =>  id !== Meteor.user()._id)

if (userIdList.length > 0)
  this.streamy = Streamy.sessionsForUsers(userIdList);

Streamy.on(this.selectedChat._id, (data) => {
  this.zone.run(() => {
    this.refreshUserActions(data)
  })
})
