How to use the chargebee.configure function in chargebee

const _refreshUserSubscriptionStatus = async (userId: string) => {
    chargebee.configure(getChargebeeOptions())

    const claims: Claims = {
        subscriptions: {},
        lastSubscribed: null,
    }

    const subscriptionQuery = {
        customer_id: userId,
        'sort_by[asc]': 'created_at',
    }

    // Query the Chargebee API for this user's subscriptions, adding every active/in_trial sub to the claims object.
    // any past subscription updates the lastSubscribed property to know whether a user has subscribed in the past.
    await chargebee.subscription
        .list(subscriptionQuery)
        .request(function(error: any, result: any) {

import Stripe from "stripe";

      if (error) return reject(error);
      resolve(result.customer as Customer);
