IVR webhook test from Postman client

I am trying to test the ivr channel for a bot using Postman.
My bot has multiple messages in sequence Ex:
User> ticket status
Message 1> One moment, I am looking up your tickets
Message 2> There are three tickets …

When I try to hit the ivr webhook endpoint

https://bots.kore.ai/ivr/hooks/?token=

with body

{
“callId”: “14077511777”,
“message”:“viewtickets”
}

The response xml only returns the Message 1 - “One moment, I am looking up your tickets”

how can I get the next Message?
