Access EKS cluster created by Gitlab

,

I used Gtlab to create an EKS cluster.

Now, I want to connect it to it but I get
error: You must be logged in to the server (Unauthorized)

My Kubectl config is created using the aws eks cli

aws eks --region eu-west-2 update-kubeconfig --name gitlab-runner

On Gitlab documenation it says " You must add your AWS external ID to the IAM Role in the AWS CLI to manage your cluster using kubectl ."

I have added the external_id of gitlab user to my default profile which has admin access.

How can I access the EKS cluster created by Gitlab?
