Setting a Matlab GUI apps main figure to invisble

I was interested in trying to break up my GUI app in to a set of smaller GUIs, all made in app creator, but using only a single app window and allowing the user to switch between them. I made a parent app with a button that when pressed started a second app containing a panel. The second app has a startup function that sets the parent of the panel to the figure window of the first app, which behaves as expected, but the second app window is still present. So then I added another line in the start up function to set its own uifigure to invisible:
% Code that executes after component creation
function startupFcn(app, parent)
app.Panel.Parent = parent;
app.UIFigure.Visible = false;
The argument 'parent' is the UIFigure from the first app.
This seems to work as expected, but what happens to the instance of app 2? The figure window is invisible, but it seems the app is still running. If so can it be closed without making it visible to user? What happens to its instance if I close the first app? Can I delete the instance from either app?

The parent app should get the other app handles when the secondary apps are created. For example,
app.SecondaryAppHandle = secondaryApp;
where SecondaryAppHandle is a property of the primary app (instructions).

Run Test2.mlapp.
Press To Plot, it will take you automatically to Test1
Test1 and Test2 must be in the same directory

How it works

Here is my version. It allows all the components to be drawn in the same uifigure. Assigning the second app to a property in the first should ensure that it is deleted correctly when the first app is closed. Assigning the calling app to a property of the callee exposes all the public properties and methods of the caller to the callee. I'm not sure whether it it better for the second app to be created and deleted on the button presses or for the first app to just check if the second app has been instantiated and use visibilty to hide/show the panel. This may be better as the second app can then be used to store data.

I found part of my answer here. Using
h = findall(0,'Type','figure');
I found I had a number of orphaned invisible figures!
