apiVersion: alloydb.gcp.upbound.io/v1beta2
kind: Instance
metadata:
  annotations:
    meta.upbound.io/example-id: alloydb/v1beta2/instance
  labels:
    testing.upbound.io/example-name: alloydb-test

    instanceType: PRIMARY
    machineConfig:
      cpuCount: 2

Steps to Reproduce

kubectl apply -f {yaml from above}

Notice that cluster and instance are created in GCP
A user is created in postgres alloydbsuperuser
List the secrets and they are empty

❯ k -n dwells get secret                                                
NAME                                                        TYPE                                DATA   AGE
alloydb-creds-cluster                                       connection.crossplane.io/v1alpha1   0      6m7s
alloydb-creds-instance                                      connection.crossplane.io/v1alpha1   0      6m7s

What happened?

I expect that the secrets are created with hostname, user, and password as mentioned in the documentation.
