net_flow_tcp_begin missing in logs

[Ziphone]

Environment

Azure AKS, K8s: 1.27, OS: Ubuntu 22.04.4 LTS, Kernel: 5.15.0-1057-azure
Installation: Helm, chart: tracee, version 0.20.0

Issue

My cluster hosts numerous services, which is reflected by a lot of net_tcp_connect, security_socket_connect, and net_packet_http_request events in the Tracee logs. Despite including net_flow_tcp_begin in my Policy resource, I don't get any such events. I have also tested tracee --output json --events net_flow_tcp_begin, with no luck.

Is this new event enabled? Could there be any gotchas I have missed out on?
