Why don't we create unique ID before we call startNewConversation?

For example,

this.startNewConversation({
  ...this.props,
  document: {
    ...this.props.document,
    conversationId: uniqueIdv4(),
    userId: uniqueIdv4()
  }
});

And can we always call setCurrentUser every time we call startNewConversation?

Your existing logic may be good or have some reasons behind, I just didn't see through it yet. If there are any, please consider me approved. 😅

I don't see why this approach wouldn't work. I actually like it a lot more than making a function call like (undefined, true, true) -- seems odd

I tried this approach out and it actually causes new livechat windows to be opened on every restart, as well as prevents webchat from connecting to directline when restarting with a new user id. I'm not entirely sure why though. I believe it might have to do with setting the current user every time.

Or should it be like this?

Suggested change

	this.startNewConversation(undefined, true);
	this.startNewConversation(undefined, true, false);
