datacursormode isn't working on a specific UIAxes for Matlab R2023a

I have MATLAB R2023a. I have a matlab app with different UIAxes. I would like to assign different custom data cursor behavior for each UIAxes. However, when I try to use:
dcm1 = datacursormode(app.UIAxes1, 'on');
set(dcm1, 'UpdateFcn', @(~, event_obj) customDataCursorForUIAxes1(app, event_obj));
I get matlab error saying: Invalid figure handle. I don't understand what's the reason behind that specifically that it's supposed to be a valid new feature:

Exactly. I just give it as an example.
When I was developing an APP, it would be like this " datacursormode(app.UIaxes_xxx, 'on')". But it doesnt work.
That is why I check datacursormode.m file and HELP.

As I emphasized ("DATACURSORMODE only works on figure handle not on axe handle yet."), the datacursormode.m is not support what HELP tell.![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1601461/image.png)

The comments have not been updated to reflect accepting an axes. The code for handling an axes starts at roughly line 117
webAxesInputArgument = (nargin > 0) && matlab.graphics.interaction.internal.isWebAxes(varargin{1});

At the time you make the call
dcm1 = datacursormode(app.UIAxes1, 'on');
app.UIAxes1 is not a valid Axes object that is parented by a uifigure .
For example it might be parented by a traditional figure, or it might have been deleted.
(Or at least toolbox/matlab/graphics/+matlab/+graphics/+interaction/+internal/isWebAxes.p cannot detect that it is an Axes parented by a uifigure. That is a .p file so we cannot check it for potential bugs involving container objects.)
