When importing managed cluster into argocd, a message is displayed indicating cluster-secret not found

[mirlad]

How is cluster-secret created in the managed cluster namespace in the central cluster and why does it not exist

Hi, you will need some external tooling to handle the secrets management in order to use the traditional ArgoCD push model.

You can try using the pull model method to avoid having to deal with cluster secrets.
