window.recaptchaCallback = ()=>{
    const t = {
        sitekey: n.N.V2_CaptchaKey,
        callback: this.onSuccessCallback.bind(this),
        "error-callback": this.onErrorCallback.bind(this),
        "expired-callback": this.onExpiredCallback.bind(this)
    };
    this.widgetId = this.renderCaptcha(t)
}
