msgraph.NewDirectoryObjectsClient().GetByIds() should provide more information in DirectoryObject

[mblaschke]

currently NewDirectoryObjectsClient().GetByIds() only provides following information:

type DirectoryObject struct {
	ODataId   *odata.Id   `json:"@odata.id,omitempty"`
	ODataType *odata.Type `json:"@odata.type,omitempty"`
	ID        *string     `json:"id,omitempty"`
}

would be good to have more information about the objects which is available in the response from MsGraph REST API, eg displayName, appId, alternativeNames, ...

or make provide a possible way to supply own struct here or only provide an dynamic interface here (to dynamically fetch data)
