Can I deploy a multiwindow app as a web app using MATLAB Web App Server?

This documentation page shows the workflow of creating a multiwindow app with the App Designer.

https://www.mathworks.com/help/matlab/creating_guis/creating-multiwindow-apps-in-app-designer.html

However, after successfully deploying and launching the app from the web app server, I get errors such as:

Web Apps does not support multiwindow apps

Or:

Error using errordlg (line 2)
Web Apps does not support errordlg.

Multiwindow apps are not supported by web apps.

This means that multiple calls to 'figure' or 'uifigure' are not supported with web apps. In addition, functions that create dialog boxes that appear as a separate window are not supported. These functions include 'dialog', 'msgbox', 'errordlg', 'warndlg', 'helpdlg', 'listdlg', 'questdlg', 'inputdlg', 'uisetcolor', and 'uisetfont'. However, functions that create dialog boxes within a figure window, such as 'uialert', 'uiconfirm', and 'uiprogressdlg', are supported with web apps.

To adjust the multiwindow app to work with MATLAB Web App Server, one possible workaround is to use a tab group to replace windowing.

1. Add a tab group that covers the entire app. 

2. Then, you can integrate different windows as different tabs. 

3. Rather than opening a new window, you may open the tab with the appropriate content instead.
