How do I know which app is showing pop-up ads?

Question

Android

Periodically, after connecting to the Internet, pop-up ads began to appear. Is there any way to determine which app is causing this ad?
After the appearance of the advertising banner, I immediately went into the settings section of the running applications. There was a single application that was launched a couple of minutes ago. The application is called Andoid Services. It has 2 services. The ad disappears after the FloatingService is stopped.
What kind of application is this and how to get rid of starting this service?
In the picture, you can see an advertising banner in the right corner.

Answer 2

When I discovered this, I waited for the next ad to appear and clicked the application manager button on the ad screen. In the dispatcher, I clicked on the window with the advertisement and held it.
