My question is specifically about [Custom Header Links (icons)](https://meta.discourse.org/t/custom-header-links-icons/86307).

What should I do if the URL is not fixed, is there a way to link to javascript to perform actions?

Hey chien!

It would require a custom script, yes. Can you explain your use case?

Thanks for the reply,  
I need to call the chat plugin to create a specific chat room,  
probably like this:

```js
  @action
  chatWithSomebody() {
    chat
    .upsertDmChannelForUsernames([somebody_name])
    .then((channel) => {
      this.router.transitionTo("chat.channel", ...channel.routeModels);
    });
  }

```
