How to restrict the ButtonDown callback to only the UIAxis part of the figure?

Hi,
I am creating an app which has multiple components in the figure. One of the functionalities I would like to have is to draw some curves in response to clicking on points in the UIAxis part of the figure. It seems that the way to go for this should be done via the UIFigureWindowButtonDown callback, but this executes at times which I don't want it to, e.g. when I am writing down parameters in edit fields.
What would be the recommended workaround?

If you observe the documentation closely for the UIFigureWindowButtonDown callback, it executes whenever a uiaxes component is triggered even though uiaxes components do not support the ButtonDownFcn property.
The following documentation link may be helpful in giving more insight about callbacks.

The issue is not that it does not trigger when I click on the uiaxis, but that it triggers when I click on other parts of the figure. What I want is for it to activate only when I click on the uiaxis.
