- Failing test: system test: default
- DataStream: event

Failure:
```
test case failed: could not find the expected hits in logs-cisco_secure_endpoint.event-33766 data stream
```

First build failed: https://buildkite.com/elastic/integrations/builds/46081

Latest failed builds:
- https://buildkite.com/elastic/integrations/builds/46123

Start with the cisco_secure_endpoint package's `system test: default` for the `event` data stream, then inspect the first and latest failed Buildkite builds linked in the issue. Confirm why the expected hits are missing from `logs-cisco_secure_endpoint.event-33766`; done means the test passes consistently in subsequent builds.
