Based on my own testing, this is combination of values that characterize each action:
| Action | id | parent_id | user_id |
|---|---|---|---|
| Physical | Not Null | Null | Null |
| Automation | Not Null | Not Null | Null |
| UI | Not Null | Null | Not Null |
A more comprehensive list of actions can be found here.
If you are saying that your testing shows that Physical and UI produce identical combinations then, unfortunately for you, there’s no available means of distinguishing between the two.
