How to make app compatible with Android 12 (Snow Cone) - ionic5

Question

I am trying to build my Ionic App to support Android 12. It works fine upto Android 11, but is not supporting Android 12.
==Supported credentials to Android 11==
package.json
“cordova-android”: “^9.1.0”
build.gradle file:
defaultBuildToolsVersion=“29.0.2”
defaultMinSdkVersion=22
defaultTargetSdkVersion=30
defaultCompileSdkVersion=30
config.xml file:
preference name="android-targetSdkVersion" value="30"
==Tried increasing sdk to 31==
package.json file:
“cordova-android”: “^10.0.0”
build.gradle file:
defaultTargetSdkVersion=31
defaultCompileSdkVersion=31
config.xml file:
preference name="android-targetSdkVersion" value="31"
added android:exported=“true” in MainActivity in ..\platforms\android\app\src\main\AndroidManifest.xml
Error :
FCMPlugin: Support for Gradle v4 or lower is deprecated. Please upgrade to a newer version.WARNING:: Configuration ‘compile’ is obsolete and has been replaced with ‘implementation’ and ‘api’.
It will be removed in version 7.0 of the Android Gradle plugin.
For more information, see Add build dependencies | Android Developers.
WARNING:: Using flatDir should be avoided because it doesn’t support any meta-data formats.

I have tried all forums and posts, nothing seem to works. Anybody has an idea on how to make this work?
