Doing POC on Virtual Agent API using Postman

[PS_1]

Hello,

Doing a POC following the documentation steps provided in https://docs.servicenow.com/bundle/vancouver-api-reference/page/integrate/inbound-rest/concept/bot-a...
Hitting the https://testabc.service-now.com/api/sn_va_as_service/bot/integration
with below request. Getting in response  "Hi, looks like you're not logged in at the moment." not sure why, as the user is logged in and has all the roles and for testing provided admin role also.
Also posted the same request with ServiceNow Rest API explorer also, still the same issue in response.
If someone has any idea, please suggest.
Request:
