Application Command Permissions

// Method 1: Define command with permissions in the command builder
const command = new SlashCommandBuilder()
  .setName('moderate')
  .setDescription('Moderation commands')
  .setDefaultMemberPermissions(PermissionFlagsBits.ManageRoles)
  .setDMPermission(false)
  ;

// Method 2: Register command with REST API
const commands = [{
  name: 'moderate',
  description: 'Moderation commands',
  default_member_permissions: '268435456',
  dm_permission: false,
  
}];

await rest.put(
  Routes.applicationGuildCommands(clientId, guildId),
  { body: commands }
);


// Command execution with permission checks
client.on('interactionCreate', async interaction => {
  if (!interaction.isChatInputCommand()) return;
  if (interaction.commandName !== 'moderate') return;

  // Permissions are automatically checked by Discord
  // Only users/roles with proper permissions can see/use the command

  await interaction.reply('Command executed!');
