Invite Members

// ignore_for_file: file_names, avoid_print

// ============================================================================
// 06 — INVITE MEMBERS
// ============================================================================
//
// Adds users to a chat directly, without going through an invite link —
// something bots generally can't do at all. Works for public
// groups/channels for any user; for private ones, you need to already be a
// member with invite rights, and the target's own privacy settings can
// still block it (that's what the returned "failed" list is for).
//
// HOW TO RUN:
//   1. Edit groupUsername and the list of usernames to invite below.
//   2. dart run example/06_invite_members.dart
// ============================================================================
