I'm being prevented from putting the email in the body of the intercom web message, every time I try to put it in, I get: POST 403 (Forbidden). Why is this happening? Can't I send the email? If the documentation says to put it in?

import * as fromIntercom from '@intercom/messenger-js-sdk';

fromIntercom.Intercom({

    app_id: this.appId,

    name: profile.nickname,

    userId: profile.sub

    email: profile.email

});
