Enable Repication Primary on GCS backend

Vault
6

This is the configuration I have (GCS backend cluster):

/vault/config $ cat extraconfig-from-values.hcl
disable_mlock = true
ui = true
listener "tcp" {
  tls_disable = 1
  address = "[::]:8200"
  cluster_address = "[::]:8201"
}
storage "gcs" {
  bucket = "some-bucket"
  ha_enabled = "true"
}
seal "gcpckms" {         
  project     = "project"
  region      = "global"
  key_ring    = "some-key"
  crypto_key  = "some-crypto"
}

I have ha_enabled. I have 3 pods with one primary and 2 standbys so I ahve ha_enbaled.

On the Raft cluster, I can enable the DR replication and then the status is enabled
Do you have any other suggestions?
