+9. Update reference iIllustrations :
+
+   Please note that if you intentionally modify the token screen, the tests will no longer work because the reference illustration will become outdated. Make sure to update the reference illustrations whenever a change is made. To do so, add the `record` parameter and set it to `true` in the `assertSnapshot` method. By default, this value is set to `false`.
+
+   After making these changes, rerun the tests to ensure everything is up to date.
+
+   Example :
+    ```text
+    assertSnapshot(of: hostingVC, as: .image(traits: UITraitCollection(userInterfaceStyle: .light)), named: snapshotName, record: true)
+    ```
