I’m trying to add or create new custom property to specific items in OneDrive. I tried using ‘openExtension’ with bellow request but failed (invalidRequest).

{
    "openTypeExtension": {
        "@odata.type": "microsoft.graph.openTypeExtension",
        "extensionName": "com.contoso.customAttributes",
        "_AlreadyCheck": "YES"
    }
}

Please suggest.
