Get a call room token

When you already know roomID but need fresh credentials for joining the room, call signalingGetTokenByRoomID():

const { data: roomCredentials } =
  await openimsdk.signalingGetTokenByRoomID(roomID);

await mediaEngine.join({
  roomID,
  token: roomCredentials.token,
  liveURL: roomCredentials.liveURL,
});

When the Promise resolves, data is a SignalingTokenResult containing token and liveURL; it does not repeat roomID. Connect to the media engine only after obtaining a valid token, using the roomID supplied to this query.

Do not enter the media room without a valid token. Call this API again when fresh room credentials are required.
