title: how to get load member list who has chatted with user A in PubNub
body: <p>Am trying to integrate the PubNub chat with react native, so I just using PubNub API for it.
  I know that PubNub is mainly working with channels. so group chats there is no issue.
  But using PubNub with one-to-one means how the channel will be created with both sides and the users should we connect at the same channel does direct channel will create the channel automatically or manually we have to create. 
  how should I display profile pic and name for both users in the member's list for both sides because User A will see User B pic and User B will see user A pic in chatted History </p>
