Unauthorized Request Error in Unity Runtime API from Zoe

I was trying out the new sketch fab api for Unity Runtime. I got the access key and secret from the support team. However, when I try to authenticate the user using email and password it throws an error “unauthorized request error”.
Here is my code


public static void Login(string _email, string _password)
    {
        SketchfabAPI.GetAccessToken(_email, _password, (SketchfabResponse<SketchfabAccessToken> answer) =>
        {
            if(answer.Success)
            {
                SketchfabAPI.AuthorizeWithAccessToken(answer.Object);
            }
            else
            {
                Debug.LogError(answer.ErrorMessage);
            }
        });
    }
    

Has anyone else tried this plug-in? Any idea what I might be doing wrong here?

Would be interested to find out if you solved this, as I’m having the same issue.
