The audit token of the process that created the flow.

## Declaration

```swift
var sourceProcessAuditToken: Data? { get }
```

## Discussion

Discussion In cases where a system process creates the connection on behalf of a source app, this value is different from sourceAppAuditToken. In cases where the source app directly creates the connection, these values are identical.
