Twilio : How to grant access to camera permanently?

I have a meeting app using Twilio Video.

The app has a requirement such that when a user wants to join a room, it's not immediate. That means a user sends a request to the app server to join, immediately he will see his local webcam, then he will wait for sometime until the server responds with a token to join the room. It may be 10 or 20 minutes.

The communication between the client and the server is done through WebSockets.

Here is the process :

Step 1: Client sends a request to the app server to join a room

Step 2: Request access and show the client local camera as follows :

// Get the track from twilio
const Track = await Twilio.Video.createLocalVideoTrack();

// Add track to HTML        
LocalMediaContainer.appendChild(Track.attach());

Step 3: Client waits for the server to respond (let's say 10 minutes)

Step 4: The server responds with the token to join Twilio video room

Step 5: Client joins room using the token sent by the server as follows

Twilio.Video.connect(Token, { name:RoomName }).then(room => {
    console.log('Successfully joined a Room');

    room.on('participantConnected', participant => {
      console.log('A remote Participant connected ');
    });
  }, error => {
    console.error('Unable to connect to Room');
  });

The process works fine. The problem I'm getting however, is that in Step 5, when the client is trying to join a room, Twilio asks him again to grant access to camera.

Basically, even though the access has already been granted, the method Twilio.Video.connect asks again for access.

I was wondering if there is a way to use the authorization previously granted to use the camera and avoid asking for it again if it has already been granted.

Twilio developer evangelist here.

When you call Twilio.Video.connect you can pass an array of tracks with the user's media that you already have.

Twilio.Video.connect(Token, { name: RoomName, tracks: [VideoTrack, AudioTrack] }).then(...);

This uses your existing tracks instead of making a new permissions request to getUserMedia.
