// Define callback as a named function
const handleClick = (value) => {
  console.log("Clicked:", value);
};

// Add listener
await api.addEventListener("product_clicked", handleClick);

// Remove specific listener
await api.removeEventListener("product_clicked", handleClick);

// Or remove ALL listeners for this event
await api.removeEventListener("product_clicked");

* Call without callback to remove all listeners for the given event name<br>
