Configure to ELK Stack with SSL

Hi, want to ask,
how to configure to interate with my existing ELK with SSL and username password with BugHound ?

example the script input on filebeat.yml or auditbeat.yml
```
output.elasticsearch:
hosts: ["https://localhost:9200"]
ssl.certificate_authorities: ["xx.crt"]
username: "elastic"
password: "password"
```

Thanks

Start by checking how Bughound connects to Elasticsearch and whether its configuration references filebeat.yml or auditbeat.yml. Document the SSL certificate authority, username, password, and Elasticsearch host requirements, with a verified configuration example and a clear way to confirm the connection works.
