Describe the problem
I don't know whether this is my own problem or not.
By following your steps, my app didn't create a channel to submit the notification.
But after I add a line "createNotificationChannel();", it works.
So I think that it might be that you forgot to add a step for creating the channel in onCreate() in MainActivity.
In which lesson and step of the codelab can this issue be found?
Lesson number + step number.
08.2 The alarm manager + step 4
How to reproduce?
What are the exact steps to reproduce the problem?
After creating createNotificationChannel(), add a step to call it in onCreate().
Versions
What version of Android Studio are you using? 2021.1.1 Patch 2
What API level are you targeting? 32

I am a Chinese student, so if you were not sure what I am saying, I can rewrite it in Chinese. Just call me.
