How to configure the new Room Finder in Outlook

The_Exchange_Team 
This week I once again tried to update the room attributes of "Conference Rooms" as well as "Workspaces" - this time via the places API.
I used MS Graph Explorer to list "all" places -- well, apparently "Workspaces" are excluded from the places API response - which I figured out later.

To list all "Conference Rooms", I used:

GET https://graph.microsoft.com/beta/places/microsoft.graph.room

 To list all "Workspaces", I used:

GET https://graph.microsoft.com/beta/places/microsoft.graph.space

So far so good.

Now I successfully updated the attributes of a specific "Conference Room":

PATCH https://graph.microsoft.com/beta/places/<placeId>
Content-type: application/json

{
    "@odata.type": "microsoft.graph.room",
    "building": "A",
    "floorNumber": 1,
    "floorLabel": "Floor Level 1",
    "label": "Building A",
    "capacity": 12,
    "audioDeviceName": "Jabra Speaker large",
    "videoDeviceName": "Beamer, ClickShare",
    "displayDeviceName": "Beamer canvas",
    "isWheelChairAccessible": false,
    "tags": [
        "RoomType: Meeting Room",
        "Equipment: Beamer"
      ]
}

Works like a charm and the updated attributes were instantly available in RoomFinder.

However, I currently struggle to update the room attributes of "Workspaces".
I can manage to get a specific "Workspace" by means of this API call:

GET https://graph.microsoft.com/beta/places/<placeId>
Content-type: application/json

When I try to update (PATCH) the attributes of a "Workspaces" place, I receive an 404 response.

*request body*
```json
{
    "@odata.type": "microsoft.graph.room",
      "building": "B",
      "floorNumber": 1,
      "floorLabel": "Floor Level 1",
      "label": "Building B",
      "capacity": 2,
      "isWheelChairAccessible": true,
      "tags": [
        "RoomType: Hot Desk"
      ]
}
```

*response*
```json
{
    "error": {
        "code": "UnknownError",
        "message": "{\"code\":\"invalid_place\",\"message\":\"place in /locations/odata/api/v2.0/places('<placeId>') not found\"}",
        "innerError": {
            "date": "2022-04-08T16:33:35",
            "request-id": "<request-id>",
            "client-request-id": "<client-request-id>"
        }
    }
}
```

I also considered to modify the @odata.type to "microsoft.graph.space" which resulted in an 400 error:

*request body*
```json
{
    "@odata.type": "microsoft.graph.space",
      "building": "B",
      "floorNumber": 1,
      "floorLabel": "Floor Level 1",
      "label": "Building B",
      "capacity": 2,
      "isWheelChairAccessible": true,
      "tags": [
        "RoomType: Hot Desk"
      ]
}
```

*response*
```json
{
    "error": {
        "code": "",
        "message": "Update request has to be for a tenant Room or RoomList.",
        "innerError": {
            "date": "2022-04-08T16:41:05",
            "request-id": "<request-id>",
            "client-request-id": "<client-request-id>"
        }
    }
}
```

How can I update "Workspaces" room attributes by means of the places API ??? HELP HIGHLY APPRECIATED
