// Extract the player's username from the command
let username = context.params.event.data.options[0].value;

// Send a response straight away, so Discord doesn't timeout if the API is slow
await lib.discord.interactions['@1.0.1'].responses.ephemeral.create({

  response_type: 'CHANNEL_MESSAGE_WITH_SOURCE',
  content: '',

  embeds: [
    {
      type: 'rich',
      title: `⏳ Looking up name history, please wait...`,
      description: ``,
      color: 0x4b6584,
    },
  ],
});

let nameHistory; // we initialise this variable here so we can access it outside the try/catch block

// Use the API to lookup this player's name history
try {
  nameHistory = await lib.minecraft.players['@0.0.1'].history({
    identity: username,
  });
} catch (e) {
  // If there's an error (probably because the username doesn't exist), show it in Discord
  return await lib.discord.interactions['@1.0.1'].responses.update({

        title: `❌ Failed to lookup name history`,
        description: `The username provided doesn't exist.`,
        color: 0xeb3b5a,
      },
    ],

// We'll render this array inside an embed in Discord

        : `Changed at ${name.changed_at}`,
  });
}

// Once we've fetched the player's name history, send it back to Discord
// As this is an ephemeral response, only the person who used the command can see it
