Cloud native gateway example helm values config?

Trying to get CNG (cloud native gateway) to work (from Cloud Native Gateway | Couchbase Docs), with no luck. It’s a great addition, but can’t seem to get it to work.
Does anyone have a simple example?
And is the TLS definition mandatory, or can it just be open as http?
And it mentions that it should get it’s own container, but there’s not a lot of docs on that…

unable to pull the cloud native gateway image, using operator 2.6.2 and couchbase server 2.6.3.
Anybody got at lease a helm definition that load the thing?
(have commented out the tls definition to get this far)

is the cloud native gateway protected? getting:

 "docker.io/library/cloud-native-gateway:1.0.0": pull access denied, repository does not exist or may require authorization: server message: insufficient_scope: authorization failed                                  │
