调用Autodesk Forge API获取项目遇404/403错误，求排查

按照官方教程尝试调用https://developer.api.autodesk.com/project/v1/hubs接口获取项目时，得到如下响应：

{
    "jsonapi": {
        "version": "1.0"
    },
    "links": {
        "self": {
            "href": "https://developer.api.autodesk.com/project/v1/hubs"
        }
    },
    "data": [],
    "meta": {
        "warnings": [
            {
                "Id": null,
                "HttpStatusCode": "404",
                "ErrorCode": "BIM360DM_ERROR",
                "Title": "Unable to get hubs from BIM360DM US.",
                "Detail": "The requested object could not be located.",
                "AboutLink": null,
                "Source": null,
                "meta": null
            },
            {
                "Id": null,
                "HttpStatusCode": "403",
                "ErrorCode": "BIM360DM_ERROR",
                "Title": "Unable to get hubs from BIM360DM EMEA.",
                "Detail": "You don't have permission to access this API",
                "AboutLink": null,
                "Source": null,
                "meta": null
            }
        ]
    }
}

已完成以下操作：

• 创建Autodesk账号
• 发送邮件至bim360appsactivations@autodesk.com将账号转为开发者账号
• 在“Add Custom Integration”中关联应用到BIM 360 Account

请问是否遗漏了关键配置步骤？
