If you would like to know when the Klyme Widget is opened or if the user has closed it, you can use JavaScript event listeners.

​
Opening the Klyme Widget

window.addEventListener("message", (e) => {
  if (e.data.event == "opened") {
    console.log(e.data);
  }
});

​
Closing the Klyme Widget

window.addEventListener("message", (e) => {
  if (e.data.event == "closed") {
    console.log(e.data);
  }
});
