 ### Updating reference snapshots

 Often a PR might make changes to the user interface, which can cause the visual regression tests to fail.

 If you want to update the reference snapshots while working on a PR you can post the following sentence as a GitHub comment:

 ```
 bot please update playwright snapshots
 ```

 This will trigger a GitHub Action that will run the UI tests automatically and push new commits to the branch if the reference snapshots have changed.
