How to initialize with `permitted_classes` for safe deserialization

[eflukx]

store = YAML::Store.new(
  store_file,
  false, # for thread_safe, true or false
  yaml_options: {
    permitted_classes: permitted_classes_list,
    aliases: true # Allow YAML aliases if you use them
  }
)

I expected this to work with a permitted classes list, but it is not and results in a Psych::DisallowedClass: Tried to load unspecified class: error
