How to Perform Learning in Agent

Summary:

Unable to perform the learning for Payable Agent

Content (please ensure you mask any confidential information):

We imported an invoice from Agent and can see its in Policy violation status. When opened can see Payment term is not detected. However I am not able to update payment term from Image (as we used to do this earlier in IDR double click and it will bring the value in UI).

This seems not working, is there any specific setup to enable. As I also see Apply learning button means it is expected to perform learning here. Any one has any idea how to perform this learning.
