Ionic Capacitor FCM , android build failing

Question

I am stuck at the below issue for quite some time and its not getting resolved, had searched across stack overflow, google, but nothing is working for me. There's a workaround suggested on ionic portal, that too is not working. Please help me to resolve the issue.

I have tried to add google-services.json in android/app directory, then the 2nd issue comes, then why I tried to add the same file android/capacitor-cordova-android-plugins directory, then another issue comes stating:

Execution failed for task ':capacitor-cordova-android-plugins:processDebugGoogleServices'. No matching client found for package name 'capacitor.android.plugins'

Below is the original issue, when google-services.json, is not placed anywhere.
