How to put any app in a resizable (freeform, pop-up) window when it starts, from MacroDroid automation macro?

I want to find how to do the question title. - Any app (and Android launcher apps, to view my home screen shortcuts, on top of all apps). - MacroDroid can send activity intent commands to Android. I want to put an app in a resizable (freeform, pop-up) window *when a device action starts it*, in that automation app macro. *Thank you for anything to help.* ---------- ***I can use Taskbar .***
