我尝试使用JWT oAuth方法通过DocuSign API进行身份验证以创建模板。我一直收到响应“You need to enable JavaScript to run this app”。我不太擅长连接API，需要一些指导。X-DocuSign-Authenticate方法可以正常工作，但DocuSign在2023年3月之后将不允许REST使用此方法。这是DocuSign演示开发者帐户。
我已经尝试了下面的代码，但不断得到相同的错误.

function createTemplate() {

    var driveFile = DriveApp.getFileById("FILEID");
    var changeorderEncode = Utilities.base64Encode(driveFile.getBlob().getBytes());

    const JWT = "MY_ACCESS_TOKEN";
    const url = 'https://account-d.docusign.com/oauth/token/restapi/v2.1/accounts/<accountid>/templates';
