I have deployed a Automation in RoboManager and assign WorkGroup and associated Workbasket with it

Now to trigger the Automation i have created a CaseType and Call the Automation package using the Case Workflow. Every Configuration is working good and i am able to trigger the Automation when i create a New case of that case type.

Problem Statement

Suppose i have 3 fields inside my CaseType below

Test1

Test2

Test3.

When i create a new case using CaseWorker Portal i can fill all the optional 3 values and click submit which will trigger the automation and my case got completed but i want i can Populate these 3 fields from my code inside automation when it triggers using the flow itsself instead of manually entring them while creatin g the case
