How can I add an info button in OSX today extension?

Question

I am looking for a way to add an "info" button on the top bar of a today extension. Just like the ones Apple uses in its own extensions in OSX. I have tried looking for ways to implement it but I can't seem to find anything.

Thanks for your help.

For those interested, I finally found the solution:

You have to implement the following methods :

   //func widgetAllowsEditing() -> Bool {
   //     return true
   // }

    var widgetAllowsEditing: Bool {
        return true
    }
    func widgetDidBeginEditing() {

     // do your stuff

    }

    func widgetDidEndEditing() {

      // do your stuff

    }
