### Describe the expected outcome The `cert-manager.io/cluster-issuer` annotation for `Ingress` should be allowed to point to a `AWSPCAClusterIssuer`. ### Describe the actual outcome To refer to a `AWSPCAClusterIssuer`, cert-manager _only_ recognizes `cert-manager.io/issuer` and _not_ `cert-manager.io/cluster-issuer`. This is counter-intuitive given that `cluster-issuer` is supposed to point to a non-namespaced resource. https://cert-manager.io/docs/usage/ingress/#supported-annotations ### Steps to reproduce 1. Deploy cert-manager and aws-privateca-issuer using Helm 2. Create a `AWSPCAClusterIssuer` 3. Create a test app with an `Ingress` and annotate it with `cert-manager.io/cluster-issuer` The result is that nothing happens at all - the annotation is effectively ignored. ### Relevant log output _No response_ ### Version 1.2.4 ### Have you tried the following? - [X] Check the [Troubleshooting section](../#troubleshooting) - [X] Search open [issues](https://github.com/cert-manager/aws-privateca-issuer/issues) ### Category Other ### Severity Severity 3
