How to insert AdMob ads in Unity (2D) in 2020?

Question

Unity

I just can’t find and make (yes, I’m not a programmer at all) code for advertising. It's the one that works for you. And you don’t need to write water in the answer like: “Read the documentation”, “You can’t find it lazy”, etc.

Answer 1

So the answer received here will also be from the Internet and, according to your tradition, will also not work.
Everything is exhaustively written in the documentation, what and where to register in order to work in 2020. Install AndroidStudio and read the logs from the phone, even there they usually write what you did wrong.
