Sorry to say this. Your documentations doesn't have "to the point" explanations. Most of the examples for helmValues are not a part of the Schema and doesn't support. For example, there is no clear explanation on the IngressRoute for TCP neither in the helm values.schema.json nor in the documentation.
Thanks for the message. I totally agree with your comment.
This product is advertised as "Cloud-native, GitOps-driven API runtime solutions for demanding DevOps and Platform Engineers" but it has one of the worst documentations I've ever seen on Kubernetes integration.
That said, unfortunately I have to sort this out in some way and might try to load the config directly from files mounted on the pods.
