How to watch youtube outside the application

[AC Question]

I was able to accidentally watch youtube outside the app. I could attach a screenshot but I don't know how.

Anyway, as I can remember there's a small circle on top of the box and I can drag it around the home screen. Also, before that happened, I remember a prompt asking me if I want to see my text messages on top or something.

I'm not sure what happened but I got redirected outside the app but I could still play it and pause and control the sliding mechanism of youtube.

Hi, what device do you have? have you tried swiping down from one of the top corners while in the youtube app?
