// 04 — PROMOTE / DEMOTE ADMIN
// ============================================================================
//
// Grants and revokes admin rights. AdminRights lets you pick exactly which
// privileges to grant — or use `.full()` for "give everything".
//
// HOW TO RUN:
//   1. Edit groupUsername and memberUsername below. Your account needs
//      admin rights with "add new admins" to promote/demote others.
//   2. dart run example/04_promote_demote_admin.dart
