Buying Items from the Shop:

The method items.buy(item_id) is used to purchase items from the shop. You can only buy items that cost 0 bubbles, are free to use, or are purchased with gold and exclusively found in the shop. The bot cannot initiate trades, exchange items with players, or purchase items from the market.

// Assuming you have defined the Highrise instance as "bot".
bot.on("chatCreate", async (user, message) => {
  if (message === "buy") {
    bot.items.buy("eye-n_basic2018malesquaresleepy").then((res) => {
      console.log(res);
    }).catch(e => console.error(e));
  }
});

The items.buy method accepts one parameter, which is the item ID. Ensure that you provide the correct item ID; otherwise, the bot will return a server error. Additionally, the bot cannot purchase items based on their name; you must specify the item ID.

This method is useful for acquiring new items from the shop to expand the bot's inventory.
