Use AdMob for AIR?!

Does anyone know how to implement AdMob ads in Adobe Flash? If so, could you help me?

I'm using a plugin, but Ad is not running.

Thanks in advance!

Here's the file's assembly:

1- I did download the SDK Air, version 31.0.0.96 and installed.

2- I did download the admob-for-flash, and I am using "admob20180711.ane" in my library.

3- I created one frame, and imput the code, one action: https://pastebin.com/LXAF5Pi1

4- I edited my XML file and added the permissions with the code: https://pastebin.com/4sMiWKYJ

I've exported, and tested the application, but the AD is not displayed.
Would you help me?
I am using the current version of your plugin, and the Air SDK 31.0.0.96.
Best regards!
