Hi sameerbimali ,
Thanks for letting us know about this!
It seems that Facebook has updated the widget and removed the close button. 🤔
We will fix this in a future update.
For now you could perhaps add this custom script into your site's header:
<script type="text/javascript">
function buttonizerInitialized() {
document.querySelector(".buttonizer").onclick = () => {
if(document.querySelector(".fb-customerchat").querySelector("iframe").style.maxHeight !== "0px") {
FB.CustomerChat.hideDialog();
}
}
}
</script>
This will make it so that when you click on the group button, it will close the Messenger Chat Widget.
Please let me know if this works for you! 😀
