CCO's ServiceAccount cannot list ConfigMaps at the cluster scope.  

1. Install an OCP cluster (4.14.0-0.nightly-2023-07-17-215017, CCO commit id = 0c80cc35f6ee4b45016050b3e5a8710a8ed4dd81) with default configuration (CCO in default mode)

2. Create a dummy CredentialsRequest as follows:
apiVersion: cloudcredential.openshift.io/v1
kind: CredentialsRequest
metadata:
  name: test-cr
  namespace: openshift-cloud-credential-operator
spec:
  providerSpec:
    apiVersion: cloudcredential.openshift.io/v1
    kind: AWSProviderSpec
    statementEntries:
    - action:
      - ec2:CreateTags
      effect: Allow
      resource: '*'
    stsIAMRoleARN: whatever
  secretRef:
    name: test-secret
    namespace: default
  serviceAccountNames:
  - default 

3. Check CCO Pod logs:
