Listing Bots in a Chat

// 24 — LISTING BOTS IN A CHAT
// ============================================================================
//
// ParticipantFilter.bots is a server-side filter — useful for chats with
// hundreds of members where paging through everyone with `.recent` to spot
// the handful of bots yourself would be wasteful.
//
// HOW TO RUN:
//   1. Edit groupUsername below to a group/channel that has at least one
//      bot in it.
//   2. dart run example/24_bots_in_chat.dart
// ============================================================================
