'generic' handleType does not trigger an event on iOS Recent's (call log) row click

Bug report

• I've checked the example to reproduce the issue.
  Can't check it, receiving this error: https://github.com/react-native-webrtc/react-native-callkeep/issues/282

• Reproduced on:

• Android

• iOS

Description

generic handleType does not work as it does with phone handleType.

Steps to Reproduce

• Run RNCallKeep.startCall('4692135d-dcbc-4a7f-aec6-ab383cd62b16', 'whatever handle you like', 'Test name', 'generic');
• End call.
• Go to iOS Recents (call log)
• Click on 'Test name' row

Expected behaviour
App is opened and didReceiveStartCallAction event is triggered.

Actual behaviour
Nothing happens

Versions

- Callkeep: 4.0.1
- React Native: 0.63.4
- iOS: 14.3
- Phone model: iPhone XS

Logs

No output has been provided after the click action.

Start by reproducing the iOS 14.3 flow with RNCallKeep.startCall using the generic handleType, then compare it with the phone handleType when selecting the call in Recents. Verify that the app opens and didReceiveStartCallAction fires for generic; the issue provides no source file or test path, so locate the iOS event-handling entry point from the reproduction.
