### View the approval flow in an envelope
1. Open an envelope in **On approval** status.
2. Scroll to **Approval flow**.
3. Expand the section.
You can see approver statuses and comments there.
### Limitations
While an envelope is **On approval**, the user who started the approval can’t continue processing the envelope.
Only the last approval run is shown in the UI. Previous approval history is available via API.
### What approvers can do
Approvers can approve or reject the envelope. They can also add a comment.
* If an approver rejects the envelope, the approval flow ends with **Rejected** status.
* If an approver approves the envelope, the flow continues to the next approver.
* When the flow finishes, the envelope returns to **Waiting** status.
