Capacitor, android onActivityResult inside plugin

I struggle to understand context activity inside Capacitor plugin.

Inside one of the plugin methods, ( I stripped the code just to show the problem)

public class GooglePayPlugin extends Plugin {
    private Activity activity;

    public void init(PluginCall call){
        activity = getActivity();
        googlePayClient.requestPayment(activity, googlePayRequest, (success, error) -> {
          if (error != null) {
            // handle error
           }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        googlePayClient.onActivityResult(resultCode, data, (paymentMethodNonce, error) -> {
        // send paymentMethodNonce.getString() to your server
    });
  }
}

How to get activity, that will call onActivityResult inside the plugin ? In example above I get onActivityResult response, but it's inside MainActivity so I don't have access to plugin properties.
