Hi There,

I noticed, by doing `RED.events.DEBUG = true` in the browser that this action:

![Screen Recording 2026-06-13 at 11.36.40](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/6/2/624c07ec652705941a7c2ea0abce14d8452653df.gif)

does not trigger an event. It would nice - since this feature is being introduced with NR5 - to have an event triggered so that custom hooks can be added (in this case adding some JS to make the grey button work).

Just an idea ...

Worked around with

```auto
        let workspaceChangedCallback = () => {
            setTimeout(() => {
                $('.red-ui-flow-node-docs g').on('click', () => { 
                    setTimeout(activateTranscriptButton, 300) 
                })
            }, 500)
        }

        RED.events.on("workspace:change", workspaceChangedCallback)

```

so no need for an extra event.
