+- [ ] I have gone through the [GitHub issues](https://github.com/espressif/esp-matter/issues) and the [Matter Programming Guide](https://docs.espressif.com/projects/esp-matter/en/latest/esp32/) and did not find a similar issue.
+- [ ] I have verified that the PICS items match the cluster configuration on my DUT.
+- [ ] I have verified that the PICS items are correct as per the test plan.
+- [ ] I have run the test locally and verified that the issue is reproducible. (You can run tests locally by following instructions here: [Python tests](https://github.com/project-chip/connectedhomeip/blob/master/docs/testing/python.md#running-tests-locally) and [YAML tests](https://github.com/project-chip/connectedhomeip/blob/master/docs/testing/yaml.md#running-yaml-tests))
