In multiple-cluster setup gui does not show anything

I've deployed Kubeopsview via Helm chart. I followed 'Static List of API Server URLs' procedure as I passed a list of API servers in CLUSTERS environment variable. I also passed required ssl certs via kubeconfig:

apiVersion: v1
clusters:
- cluster:
    certificate-authority: /etc/sec/ca.pem
    server: https://master.01.test.com
  name: 01
- cluster:
    certificate-authority: /etc/sec/ca.pem
    server: https://master.02.test.com
  name: 02
- cluster:
    certificate-authority: /etc/sec/ca.pem
    server: https://master.03.test.com
  name: 03
contexts:
- context:
    cluster: 01
    namespace: default
    user: 01
  name: 01
- context:
    cluster: 02
    namespace: default
    user: 02
  name: 02
- context:
    cluster: 03
    namespace: default
    user: 03
  name: 03
current-context: 01
kind: Config
preferences: {}
users:
- name: 01
  user:
    client-certificate: /etc/sec/01.pem
    client-key: /etc/sec/01-key.pem
- name: 02
  user:
    client-certificate: /etc/sec/02.pem
    client-key: /etc/sec/02-key.pem
- name: 03
  user:
    client-certificate: /etc/sec/03.pem
    client-key: /etc/sec/03-key.pem

After deployment I looked into pod logs:

INFO:kube_ops_view.main:Listening on :8080..
INFO:kube_ops_view.update:Discovered new cluster 01 (https://master.01.test.com).
INFO:kube_ops_view.update:Discovered new cluster 02 (https://master.02.test.com).
INFO:kube_ops_view.update:Discovered new cluster 03 (https://master.03.test.com).

It seems fine, however kubeopsview gui shows nothing. Any idea why it does not work? Thanks.

NOTES:
To access the Kubernetes Operational View UI:

1. First start the kubectl proxy:

   kubectl proxy

2. Now open the following URL in your browser:

   http://localhost:8001/api/v1/proxy/namespaces/kubeopsview/services/kubeopsview/

Please try reloading the page if you see "ServiceUnavailable / no endpoints available for service", pod creation might take a moment.
