Quickblox changing the opponent in 1 to 1 chat

I am using the the latest version of quick blox from

Here i am using the demo 1-1 chat and i have changed it to the user of the app that i have created

enter image description here

It is working good, and i can able to login

But after the login i can see only the opponent as Quick always like the below screen

enter image description here

How can i add another user of my application as opponent ?

I can find that the opponent was declared here

var opponent = chooseOpponent(chatUser.login);

But where does the chatUser.login comes from.

So, I don't know how to have the opponent as the some user ? How can i have it ?

Solution

I suggest you to use latest Chat updates here

The sample you use is from deprecated js sdk
