      JSON specifying filter conditions.
      Accepts the same format as returned by the [queries](https://www.openproject.org/docs/api/endpoints/queries/) endpoint.
      Currently supported filters are:

      + grantable: filters roles based on whether they are selectable for a membership

      + unit: filters roles based on the unit ('project' or 'system') for which they are selectable for a membership
    example: '[{ "unit": { "operator": "=", "values": ["system"] }" }]'
