The above is correct.
SSH "may" have its own way to keep alive, but that would
be a different implementation altogether.
SSH does indeed have its own keepalive. Search for ServerAlive in
ssh_config(5) and ClientAlive in sshd_config(5) if you want details. It
is an entirely different mechanism from (D)TLS heartbeat.
hope this helps,
