Show "close app" when run in silent mode

Hi there,

we want to use PSADT to deploy a bunch of application with Intune. Therefore we want use the deploymode="silent" parameter and want to show the GUI only if an application is open. All applications are listed in the command

Show-InstallationWelcome -CloseApps 'java,iexplore=Internet Explorer,firefox=Mozilla Firefox,chrome=Google Chrome,javaw,tws' -AllowDefer -DeferTimes 3

In the following post in this forum nicolas-2 also ask for this feature and @richard-3 made a fork of PSADT. (here)
But i think this switch (-ShowClosingAppsInSilent) from richard-3 never reached the original Toolkit.

Is there any comparable function already integrated, that I can use with the deployment via Intune? I only want to show the window if one of the application is opened - no other GUI window should be displayed.
