Looking at this document it mentions using a Squid integration for Elastic Agent: Squid Logs | Elastic docs
However, In my 8.8.1 Fleet server /app/home#/tutorial/squidLogs only has instructions for Filebeat, which I get for beta software. Yet despite the first link specifically stating "Collect and parse logs from Squid devices with Elastic Agent.", I cannot find any reference on how to try this with Elastic Agent.
Am I missing a flag somewhere to enable beta integrations?
