How to have the mouse cursor automatically select a text box in App Designer when you open an App?

Many apps or websites will have the cursor already be inside a text box so it is not necessary to click on it to begin typing. Is this feature possible in Matlab App Designer? If so, how is it done?

The feature already is available in Guide, as seen here:

In R2022a and later releases, you can use focus function.

For example, you can add the following line to the app's StartUpFcn in App Designer:

focus(app.EditField) % or whatever the EditField handle is

In R2021b and earlier releases, there is no way to have the cursor automatically select the text box in App Designer. However, you can focus on an object in the GUI by pressing the Tab key.
