How to retrieve the Bearer token from the On-Premise Orchestrator using the HTTP Request Activity via a Basic Authentication?

For a VB project use the below details in the workflow

Timeout (milliseconds): 30000

AcceptFormat: ANY

RequestMethod: POST

Request URL: "https://ORCHESTRATOR_HOSTNAME/api/Account/Authenticate"

Body: 
"{""tenancyName"": ""TENANT_NAME"",""usernameOrEmailAddress"": ""USERNAME"",""password"": ""PASSWORD""}"
