How to use the otpauth.TOTP function in otpauth

async function submit() {
            const url = getUrl();
            const elements = await waitElements({
                twoFactorCode: () => document.getElementById("twoFactorCode") as HTMLInputElement,
                submit: () => document.getElementById("login_btn_2fa") as HTMLElement,
            });
            const $ = (window as any).$;
            const $formController: any = $(elements.twoFactorCode().form).data("$formController");
            const totp = new TOTP({
                digits: 6,
                period: 30,
                secret: Secret.fromB32(password),
            });
            const token = totp.generate();

            $formController.twoFactorCode.$setViewValue(token);
            $formController.twoFactorCode.$render();

            elements.submit().click();

            await new Promise((resolve) => setTimeout(resolve, submitTimeOutMs));

            if (getUrl() === url) {
                throw new Error(errorMessage);
            }
