How to list users in group email in Microsoft Graph?

Is there a Microsoft Graph API to list users in group email like the feature Outlook has?

If this API exists, when use it on

[email protected]

it will list

 - [email protected]
 - [email protected]
 - [email protected]
 - etc.

UPDATE 1: tried

GET /groups/[email protected]/members

on Graph Explorer (have access Directory.ReadWrite.All)

But error 400

{
    "error": {
        "code": "Request_BadRequest",
        "message": "Invalid object identifier '[email protected]'.",
        "innerError": {
            "request-id": "dad057af-2b67-4186-bc8c-df2b10fc2d0c",
            "date": "2018-02-02T09:53:51"
        }
    }
}

UPDATE 2: tried

GET /groups?$filter=mail eq '[email protected]'
GET /groups?$filter=mailNickname eq 'group1engineers'

Both get same results, still no group members show up (this group has 7 members):

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#groups",
    "value": [
        {

            "preferredDataLocation": null,

            ],
            "renewedDateTime": "2017-09-01T08:13:42Z",
            "securityEnabled": false,
            "visibility": null
        }
    ]
}

Yes, you can get the group members using the Graph API. From https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/group_list_members:

GET https://graph.microsoft.com/v1.0/groups/{id}/members

Note that it isn't transitive, so if a group contains another group, you have to run through all the children.

To search for the group and get its members at once, you can use the $filter and $expand query parameters:

https://graph.microsoft.com/v1.0/groups?$filter=mailNickname eq 'group1engineers'&$expand=members

The documentation contains information about which properties that can be $filter'ed. Look for the text "Supports $filter" in the property descriptions.
