Twilio Video narrowed its focus.
Here's why teams are migrating.

// Before: Twilio AccessToken + VideoGrant
const token = new AccessToken(accountSid, keySid, keySecret,
  { identity: 'alice' });
token.addGrant(new VideoGrant({ room: 'my-room' }));

// After: standard JWT signed with your own secret
import jwt from 'jsonwebtoken';
const token = jwt.sign(
  {
    sub: 'alice',
    tenantId: 'my-tenant', // ← required
    role: 'participant',  // ← host | participant | observer
  },
  process.env.JWT_SECRET,  // ← your secret
  { expiresIn: '1h', audience: 'tomatortc' }
);
res.json({ token });

// Before: twilio-video
import { connect } from 'twilio-video';
const room = await connect(token,
  { name: 'my-room', audio: true, video: true });
await room.localParticipant.publishTrack(localVideoTrack);

// After: @rtc-sdk/client-browser
import { createRtcClient } from '@rtc-sdk/client-browser';
const client = createRtcClient({
  signalingUrl: 'wss://your-server',
  authToken: token,
  displayName: 'Alice',
});
const room = await client.joinRoom('my-room');
await room.publishCamera();      // convenience
await room.publishMicrophone();  // convenience
// or: room.publishTrack(mediaStreamTrack, { kind: 'video' })
