Problem: Resize the iframe when any content changes inside it

Solution: We need to implement the MutationObserver inside the iframe to use the postMessage API to post a message to the parent window.

// Function to send a message to the parent to request resizing
    function resizeParentIframe() {
        const message = "resizeIframe";
        window.parent.postMessage(message, "https://parent-domain.com");
    }

    // Set up a Mutation Observer to detect changes in the iframe content
    const observer = new MutationObserver(function (mutations, observer) {
        for (let mutation of mutations) {
            if (mutation.type === "childList") {
                // Content has changed; trigger a resize
                resizeParentIframe();
                break; // Exit the loop after the first mutation
            }
        }
    });

    // Specify the target node for the observer (the body of the iframe)
    const targetNode = document.body;

    // Configuration options for the observer (you can customize these)
    const config = { childList: true, subtree: true };

    // Start observing the target node for changes
    observer.observe(targetNode, config);
