here i'm implemented SAP chatbot with hcp.
find in bellow screen shots for how my chatbot is working now.
1. here i have created 2 intent POAVAIL,PODETAIL to get List of PO Numbers and Item details of perticular PO Number respectively.



2. find bellow screen shot for how the data is coming on chatbot

But here after displaying the output of PO Item Details i need to display 2 buttons for Approve and Reject . then if the user press the Approve/Reject button then i need to pass that text as well as that PO Number into my xsjs through webhook. and have to do the Approve or Rejection function in backend.
Please suggest me how to do it.
