[ARCHIVED] Is there a way to change the rate to this way: only after the agent leave the live chat session, then the customer can rate?

In my mind, it is a bit interrupted to the CSR if the CSR meet an irational customer, who tap the thumb up / thumb down sign alternately during the live chat session.

Besides, the CSR may negotiate with the customer to change the bad rating to the good rating. If this case happened, the CSR will not focus on the customer's issue dedicately.
