Messaging App - Widget?

[userQNccDYGM8y]

I recently - somehow, added the messaging app to the home screen. This messaging app had a unique feature/user interface that I have not been able to replicate.  It showed a small window showing the messages and I could then enlarge it to see full screen or minimize it. In the few moments that I was playing around, I somehow deleted it. 

I cannot replicate this app again. It was almost like a widget, but the messaging app does not have a widget. I know how to put the messaging app back on my home screen. This is not what I am asking. It is the unique user interface that I cannot find how to replicate.

Thanks

Something along the lines as in my screenshot ?

Yes!

That is what it was. Can't find how to get it back.

Open messaging app

Tap or swipe Recents on bottom Navigation bar

messaging app will "zoom out" so you can see currently running apps - see screenshot

Next , long press on the app's icon at top middle as highlighted in other screenshot, then choose Open in Pop-up View

BTW ... you can pretty much do that with all apps
