Twilio Video - Catch "Ringing" event at web

I need to show the 'Ringing...' text on the web if the target starts ringing for that I need to capture the ringing event somewhere.

Here is my function:

registerRoomEvents(room: Video.Room) {
    room
      .on('participantConnected', this.addParticipant)
      .on('participantDisconnected', (participant) => {
        this.removeAwaitingParticipant(participant.identity);
      })
      .on('disconnected', this.onRoomDisconnection)
      .on('dominantSpeakerChanged', this.onDominantSpeakerChanged);
  }

Please help how can I capture the ringing event?

You appear to be using the Twilio Video API, which doesn't have a ringing event.

When you connect to a Twilio Video room, you connect immediately. There's no concept of ringing or waiting to connect for any reason, unless you have built that into your own application.

All the events that a Video Room fires can be found in the documentation.
