Mac Catalyst app: how to close a window without terminating the app?

Question

I'm developing an app by using Mac Catalyst.

When user has closed the window on Mac version, the app is terminated.

It was possible to change this behavior in Cocoa by using:

applicationShouldTerminateAfterLastWindowClosed

method or by setting NSSupportsAutomaticTermination to NO in plist file.

How can I get the same in a Mac Catalyst app?

UPDATE: Apple Engineering team has provided the following information regarding this issue and it worked for me:

We were able to prevent the quitting behavior by adding NSSupportsAutomaticTermination = NO to info.plist
