Can not access exposed Swiper Instance

## Prerequisites

- [x] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
- [x] The issue still exists against the latest stable version of Elementor.

## Description

as described here: https://developers.elementor.com/expose-swiper-in-elementor/ this does not work as already answered in the comments of the article. the example code always returns "undefined". Probably there is the need to wait for a certain event to call for.

## Steps to reproduce
1. Add an image carousel to an Elementor page/post.

2. Edit the widget > Go to Advanced > Advanced

3. Give the widget a unique class name/ID in the “CSS ID” or “CSS Classes” field.

4. In your Javascript file, create a jQuery instance of the carousel’s 'swiper-container' element using the ID/class you chose and the 'swiper-container' class (replace #my-id with your ID/class):

const imageCarousel = jQuery ( '#my-id .swiper-container' );
5. Now, get the Swiper instance by querying your carousel instance’s data cache using the key 'swiper':

const swiperInstance = imageCarousel.data( 'swiper' );

write console.log(swiperInstance);

## Isolating the problem

- [x] This bug happens with only Elementor plugin active (and Elementor Pro).
- [x] This bug happens with a default WordPress theme active.
- [x] I can reproduce this bug consistently using the steps above.
