/**
 * @param attendeeId Internal Amazon Chime `AttendeeId` created by [`CreateAttendee`](https://docs.aws.amazon.com/chime/latest/APIReference/API_CreateAttendee.html) API.
 *
 * @param present Indicates the attendee's presence in a meeting.
 *
 * @param externalUserId Indicates the attendee's `externalUserId` provided while joining a meeting.
 *
 * @param dropped Indicates whether the attendee dropped from the meeting.
 *
 * The Amazon Chime SDK for JavaScript reconnects a meeting session in below scenarios:
 *
 * - No audio packets (WebRTC)
 * - Bad audio delay (WebRTC)
 * - No pong reply (WebSocket)
 *
 * This value is provided by the Amazon Chime backend when an attendee is dropped and could not join the same meeting again due to re-connection issues.
 * It is also provided to differentiate the scenarios between normal attendee leave and the attendee dropping due to re-connection issues.
 *
 * In re-connection scenarios, if an attendee drops and could never join back successfully, the JS SDK will call this callback setting
 * the `dropped` value to a boolean value received from Amazon Chime backend, and it will set the `present` parameter to `false`.
 *
 * @param posInFrame This object indicates which attendee out of how many total attendees the update is for.
 * For example, if you were to join on a call with 3 total attendees, you would get presence callbacks for attendeeIndex 0, attendeeIndex 1, attendeeIndex 2 out of the total attendeesInFrame of 3.
 * You will receive callback for each attendee present in the meeting after you join the meeting. Later, you will receive callback as attendees leave or join the meeting.
