You should drag a task state and modify `IsForCompensate` to true.
```yaml
{
"Name": "ServiceTask-ht3fqkj",
"IsForCompensation": true,
"Input": [
{}
],
"Output": {},
"Status": {},
"Retry": [],
"ServiceName": "",
"ServiceMethod": ""
}
```
And then drag a line from actual task to the compensation, you will get shapes like following,

I understand, thank you
