"Capacitor Community Missing" - com.getcapacitor.community.admob.AdMob.class

Hi:

I’m trying to activate AdMob with capacitor with the AdMob capacitor community plugin at:

but there is a problem activating it because the “Capacitor Community Missing” in the MainActivity at:
com.getcapacitor.community.admob.AdMob.class

\android\app\src\main\java***\MainActivity.java

What to do? How to activate AdMob?
