How to specify service account?
i try as following but not work.

What might the configuration look like?

serviceAccount:
  # -- Specifies whether a service account should be created
  create: false
  # -- Annotations to add to the service account
  annotations:
    eks.amazonaws.com/role-arn: arn:aws:iam::937712594651:role/everc-cloudwatch-exporter-role
  # -- The name of the service account to use.
  # If not set and create is true, a name is generated using the fullname template
  name: ""

Anything else?
