+ * WithAppInitiatedAction:
+ * - Purpose: Tests when the update password action was triggered by an app.
+ * - Scenario: Simulates the case where the user presses a 'change password' button in an app and is redirected to Keycloak to change it.
+ * - Key Aspect: Ensures the 'Cancel' button is shown correctly, which displays only when the action is app initiated.
