How can I make the numeric edit field blank?

Hi. I have a question about numeric edit field object when using App Designer.

I want to make the numeric edit field blank, but it shows that 'AllowEmpty' property is off.

However, I can't find the 'AllowEmpty' property at App Designer.

Isn't it possible to make numeric edit field blank?

You can set the ValueDisplayFormat property to %0.0d

It appears the .AllowEmpty property is available but hidden (not listed; no autocomplete)

The following works (R2023a):

classdef xEmptyNumField < matlab.ui.componentcontainer.ComponentContainer

    % Properties that correspond to underlying components
    properties (Access = private, Transient, NonCopyable)
        allowEmptyButton  matlab.ui.control.StateButton
        xview             matlab.ui.control.NumericEditField
    end

   ...

    % Callbacks that handle component events
    methods (Access = private)
        % Value changed function: allowEmptyButton
        function allowEmptyButtonValueChanged(comp, event)
            comp.xview.AllowEmpty = comp.allowEmptyButton.Value;
        end
    end
    ...
        
end
