/**
 * useIapUserData hook should be called in your main screen component. This hook automatically invokes
 * getUserData API and populates states during main screen launch and App state transitions from BG -> FG.
 * "iapUserData" state returned by this hook will help you to make sure that you retrieve the
 * receipts for the current user account.
 *
 * This hook handles case where the user switched account when your app went to background. State
 * "iapUserData" will be populated when the app comes to foreground and would trigger your logic
 * to retrieve receipts for the current user.
 *
 * ```ts
 * Sample Usage:
 *    export const AppMainPage = () => {
 *       // Calling useIapUserData in main screen
 *       const {iapUserDataLoading, iapUserDataError, iapUserData} = useIapUserData({});
 *       ...
 *       ...
 *       // Once Userdata is loaded, call handler
 *       if (!iapUserDataLoading) {
 *          if (iapUserDataError) {
 *             // Handle Error based on iapUserData.responseCode
 *             ...
 *          } else {
 *             // Persist the iapUserData.userId and retrieve receipts for this user.
 *             ...
 *          }
 *       }
 *       ...
 *    }
 * ```
 *
 * @param getUserDataRequest User Data request parameters
 * @returns States and value of user data
