Can't create external initiators from chainlink CLI

We're trying to set external initiators to our chainlink containers deployed in GKE cluster according to the docs: https://docs.chain.link/docs/external-initiators-in-nodes/

I log into the the pod:

kubectl exec -it -n chainlink chainlink-75dd5b6bdf-b4kwr -- /bin/bash

And there I attempt to create external initiators:

root@chainlink-75dd5b6bdf-b4kwr:/home/root# chainlink initiators create xxx xxx
No help topic for 'initiators'

I don’t even see initiators in chainlink cli options:

root@chainlink-75dd5b6bdf-b4kwr:/home/root# chainlink
