Why can't I use app.UIAxes.CurrentPoint in MATLAB R2018b AppDesigner?

I am currently working with MATLAB R2018b and R2020a AppDesigner.

I need to use the property CurrentPoint of the UIAxes, not the UIFigure, to read the current mouse position when the mouse is on a Axes. Then I use the current mouse X position to read the corresponding Y value of a plotted line in the Axes. I use this command app.UIAxes.CurrentPoint.

It works perfectly in r2020a, but there is no property CurrentPoint of Axes in r2018b, although this website UIAxes Properties -> Interactivity -> CurrentPoint is introduced in R2016a.

Is there anyway to work around this problem?

Thank you very much!

CurrentPoint property for uiaxes was introduced from R2019a. uiaxes was introced in R2016a.
