[Question] Is there a way to use the `.UserTask` with a custom data structure instead of a plain `string`?

Is there a way to use the `.UserTask` with a custom data structure instead of a plain `string`?

Maybe with a custom `StepBody` and custom data model or something.

So with reference to:


I need to be able to pass in the **username** and **rejection reason** so I can capture that information.

So here, where I call...

```cs
await _workflowService.PublishUserAction(actionKey, username, optionValue);
```

...in my web api controller I can pass more than just the option value and consume that from a step.

Also how do I access the `username` passed in here in which ever of the `StepBody`s get called so i can assign this to the workflow data item?

Start by tracing the mentioned PublishUserAction call and the UserTask and StepBody entry points to see how action data is represented and exposed to workflow steps. Confirm whether username and rejection reason can be carried together, and define a supported usage or clearly document the limitation and expected data flow.
