Argocd-Image-updater registry custom TLS certificate add/skip issue

[Muhammad-Irfan324]

Describe the bug
https://github.com/argoproj/argo-helm/blob/ebb2d15f1e370e6023770713596aa480c71b8914/charts/argocd-image-updater/values.yaml#L149
registries:
- name: name of the registry
prefix: name of the registry
api_url: https://registryURL:443
credentials: pullsecret:namespace/secret
insecure: true

Docker registry is nexus with self signed SSL/TLS

For Docker login to local system

crt needs to be store after that docker login can be done

But argocd-image-updater says it can't find the tls verification even though passed the insecure flag

https://github.com/argoproj/argo-helm/blob/main/charts/argocd-image-updater/values.yaml

Even tried to add TLS certificate with volume and volumemount the secret and with init container or directly as well but pod goes into crashloopback error.

Version

No Option for adding CA for registry? niether the flag is working to bypass the TLS
