**As** an API client
**I want to** be able to toggle emoji reactions on a work package comment

**Acceptance criteria**

* User with "Add Comments" permission is able to add/remove an emoji reaction

* User with "Write Internal Comments" permission is able to add/remove an emoji reaction from an internal comment

* It is NOT possible to add/remove emoji reactions if the above permissions are missing


**Technical notes**

PATCH /api/v3/activities/{id}/emoji\_reactions

```json
{
"reaction": Begin of the insertion"thumbs_up"End of the insertion Begin of the deletion "thumbs_up",
"reactingUserId": "123"End of the deletion
}
```

**Permissions and visibility considerations**

* Visible to users with "Add Comments" or "Write internal comments" permissions
