Oracle Digital Assistant - post chat survey feedback

Hi Team,

Enabled Feedback component(component: "System.AgentConversation") within ODA when the live agent conversation ended with customer.

Can we update the customer feedback text on the same incident which was created in B2C while agent chatting with customer? 

Technically, checking the feasibility to update the customer feedback text “${system.userFeedbackText.value} “on the same incident via REST Service actions using Incident ID or Reference number(we can handle this using custom script or API), so is there any feasible way to get the B2C chat incident ID or Reference number back to ODA when agent wrap up or close the chat.
