    .PARAMETER Fields
        Specify a list of fields to return. The default is to return all fields.

    .PARAMETER OrderBy
        Optionally return the list ordered by a particular value. If sorting is allowed on non-flat hierarchical resources, the service should implement a qualified naming scheme such as dot-qualification to reference data down the hierarchy. Using 'asc' or 'desc' as a suffix will change the ordering, with ascending as default.
