I tried to add gitlab-agent to the environment and select the namespace and flux customization there, but I get errors

I’m using the Gitlab hosted version of Self-Manager on Kubernetes.

Install command gitlab-agent

helm upgrade --install h gitlab/gitlab-agent 
    --namespace gitlab-agent-h 
    --create-namespace 
    --set image.tag=v17.2.2 
    --set config.token=token 
    --set config.kasAddress=wss://kas.domain.com

Configuration gitlab-agent to path .gitlab/agents/my-agent/config.yaml in repository

user_access:
  access_as:
    agent: {}
  groups:
    - id: LearnHub
    - id: LearnHub/Frontend
    - id: LearnHub/Identity
ci_access:
  groups:
    - id: LearnHub
    - id: LearnHub/Frontend
    - id: LearnHub/Identity

Install command flux

flux bootstrap gitlab 
--hostname=gitlab.domain.com 
--owner=Flux-LearnHub 
--repository=Flux 
--branch=main 
--path=clusters/production 
--deploy-token-auth

Adding a repository

flux create source git learnhub-mainpage 
  --url=https://gitlab.domain.com/learnhub/frontend/mainpage.git 
  --branch=main 
  --interval=1m 
  --namespace=flux-system 
  --username=username 
  --password=token

flux create kustomization learnhub-mainpage-kustomization 
  --source=GitRepository/learnhub-mainpage.flux-system 
  --path="./manifests" 
  --prune=true 
  --interval=5m 
  --namespace=flux-system

And I don’t see Flux customization or namespace in the selection

I tried to manually grant the gitlab-agent cluster admin role for testing

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: gitlab-agent-cluster-admin
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: learnhub-gitlab-agent # name ServiceAccount
  namespace: gitlab-agent

And I made sure that gitlab-agent has rights to all namespaces, but still nothing appears in the list, tell me how to fix this.
