Update Presence

await sock.sendPresenceUpdate("available", id);

This lets the person/group with id know whether you're online, offline, typing etc.

presence can be one of the following:

type WAPresence =
  | "unavailable"
  | "available"
  | "composing"
  | "recording"
  | "paused";

The presence expires after about 10 seconds.

note

In the multi-device version of WhatsApp -- if a desktop client is active, WA doesn't send push notifications to the device. If you would like to receive said notifications -- mark your Baileys client offline using sock.sendPresenceUpdate('unavailable')
