UserInteractions {"mode":"interactions","type":"click","recordingId":"1ee752f4-9be3-4845-acad-746c46ce9cfa"}
→ # User Interactions

**Filter:** click only
**Showing 1–2 of 2 interactions**

| # | Time | Type | Detail | Point |
|---|------|------|--------|-------|
| 0 | 245158ms | click | Click at (769, 138) | Point:1 |
| 1 | 265962ms | click | Click at (1155, 652) | Point:2 |

## Next Steps

- Use DescribePoint with a point reference to inspect the code at a specific interaction
- Use Evaluate with a point reference for ad-hoc value inspection at that moment
- Use `type: 'click'` or `type: 'keypress'` to filter by interaction type
