I'm following this doc https://cloud-provider-vsphere.sigs.k8s.io/tutorials/kubernetes-on-vsphere-with-kubeadm.html
I am using a load balancer as my ControlPlaneEndpoint, now I would like to join a new master to the cluster passing the cloud-provider flag as well, through the below method it was possible join the workers however I can't do the same with a new Master.
kubectl -n kube-public get configmap cluster-info -o jsonpath='{.data.kubeconfig}' > discovery.yaml
# tee /etc/kubernetes/kubeadminitworker.yaml >/dev/null <<EOF
apiVersion: kubeadm.k8s.io/v1beta1
caCertPath: /etc/kubernetes/pki/ca.crt
discovery:

The first Control Plane was created the following way:
kubeadm init --config kubeadminit.yaml
apiVersion: kubeadm.k8s.io/v1beta2
bootstrapTokens:
- groups:
- system:bootstrappers:kubeadm:default-node-token
token: y7yaev.9dvwxx6ny4ef8vlq
ttl: 0s
usages:
- signing
- authentication

I tried to join the second master the following way however it is jointed as a worker node:
kubeadm join --config kubeadminitSecondmaster.yaml
