How to configure GCS repository for Elastic Cloud

[nuwancs (Nuwan Chamara)]

Hi There,
I am trying to create snapshots from Elastic cloud to google storage.
Documentation for the task is here.
As per the doc I have created a bucket,
created a service account and also created a key file.
And then it was added to the elastic cloud admin console

{
  "type": "gcs",
  "settings": {
"bucket": "name-of-bucket",
"region": "region-of-bucket-same-as-cluster",
"access_key": "YOURKEYHERE",
"secret_key": "secret-key-with-just-permission-to-that-bucket-do-not-use-a-master-key",
"compress": true
  }
}

Now the problem is how can I get the values for access key and for secret key?
