  /**
   *  Optional. The filter to list results by.
   *  General `filter` string syntax:
   *  `<field> <operator> <value> (<logical connector>)`
   *  *   `<field>` can be `name`, `labels.<key>` for map field, or
   *  `attributes.<field>` for attributes field
   *  *   `<operator>` can be `<`, `>`, `<=`, `>=`, `!=`, `=`, `:`. Of which `:`
   *      means `HAS`, and is roughly the same as `=`
   *  *   `<value>` must be the same data type as field
   *  *   `<logical connector>` can be `AND`, `OR`, `NOT`
   *  Examples of valid filters:
   *  *   `labels.owner` returns namespaces that have a label with the key
   *      `owner`, this is the same as `labels:owner`
   *  *   `labels.owner=sd` returns namespaces that have key/value `owner=sd`
   *  *   `name>projects/my-project/locations/us-east1/namespaces/namespace-c`
   *      returns namespaces that have name that is alphabetically later than the
   *      string, so "namespace-e" is returned but "namespace-a" is not
   *  *   `labels.owner!=sd AND labels.foo=bar` returns namespaces that have
   *      `owner` in label key but value is not `sd` AND have key/value `foo=bar`
   *  *   `doesnotexist.foo=bar` returns an empty list. Note that namespace
   *      doesn't have a field called "doesnotexist". Since the filter does not
   *      match any namespaces, it returns no results
   *  *   `attributes.managed_registration=true` returns namespaces that are
   *      managed by a GCP product or service
   *  For more information about filtering, see
   *  API Filtering (https://aip.dev/160).

  // const filter = 'abc123'
  /**
   *  Optional. The order to list results by.
   *  General `order_by` string syntax: `<field> (<asc|desc>) (,)`
   *  *   `<field>` allows value: `name`
   *  *   `<asc|desc>` ascending or descending order by `<field>`. If this is
   *      left blank, `asc` is used
   *  Note that an empty `order_by` string results in default order, which is
   *  order by `name` in ascending order.
