+### **Additional Note**
+
+In addition to the operations history, Copilot maintains a cache. If you need to ignore the current cache for any reason (e.g., when adding an action to the API driver), you can set the environment variable process.env.COPILOT_OVERRIDE_CACHE to "true" before running your tests. This will ensure that the current cache is not taken into consideration.
+```bash
+process.env.COPILOT_OVERRIDE_CACHE = "1"
+```
