I have a plot with some text annotations, added using fig.add\_annotation(). How can I trigger a callback when the annotation is clicked? clickData property of the graph doesn’t trigger

Hey @kiteme, there are no events fired when clicking annotations. The only event I know of is the relayoutData if changing a annatation:

Suppose you have a rectangular shape and change it’s dimension or position by dragging the shape.

You could also add an EventListener either JS or [dash-extensions](https://www.dash-extensions.com/components/event_listener) and trigger a callbcak if the click coordinates are within the coordinate range of your annotation.
