I am trying to register capacitor v3 plugins to Android but nothing works

I am using Ionic 5, Capacitor 3, Android 4.2.2 Node 14...etc

I am trying to install capacitor plugins geolocation and storage in Android like so:

package io.ionic.seakah;

import android.os.Bundle;
import com.capacitorjs.plugins.storage.StoragePlugin;>>>ERROR...cannot resolve symbol
import com.capacitorjs.plugins.geolocation.Geolocation;
import com.getcapacitor.BridgeActivity;

public class MainActivity extends BridgeActivity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    registerPlugin(StoragePlugin.class); >>>ERROR...cannot resolve symbol
    registerPlugin(Geolocation.class);>>>ERROR...registerPlugin not recognized

    // Initializes the Bridge
    // this.init(savedInstanceState, new ArrayList<Class<? extends Plugin>>() {{
       //Additional plugins you've installed go here
       //Ex: add(TotallyAwesomePlugin.class);

   // }});
  }

first thing of note is that the init method is deprecated and the add() is replaced with registerPlugin()...the problem is after all the adjustments the plugins aren't recognized... I have made sure to run npm cap sync and also rebuild from inside Android studio. The existing documentation mostly speaks to Capacitor V2. would appreciate any help here...Thanks
