Is it possible to configure image updater to change only image tag with helm values

[KonstantinNosov]

in docs there are described 2 ways of configuration:

name and tag

argocd-image-updater.argoproj.io/<image_alias>.helm.image-name: <name of helm parameter to set for the image name>
argocd-image-updater.argoproj.io/<image_alias>.helm.image-tag: <name of helm parameter to set for the image tag>

spec:

argocd-image-updater.argoproj.io/<image_alias>.helm.image-spec: <name of helm parameter to set for the canonical name of image>

I have helm chart that defines image with 3 values

image:
  registry:
  repository:
  version:

so neither of two documented options work. Ideally i need just image.version be updated to imgae updater determined tag , but even if i have argocd-image-updater.argoproj.io/<image_alias>.helm.image-name: "" or not set helm.image-name annotation at all it uses default 'image.name' and adds value...

Adding dummy .helm.image-name does not work as chart has json schema validation
