    // CANDIDATE TASK: Write code that will star a message when you react to it with a heart emoji
    //
    // Hints:
    // 1. You'll need to listen for reaction events using Store.Reactions
    // 2. Check if the reaction is a heart emoji (❤️)
    // 3. Use Store.Msg to get the message object
    // 4. Use Store.Chat to get the chat object
    // 5. Use Store.Cmd.sendStarMsgs to star the message
    //
    // Your code should detect when the user adds a heart reaction and then
    // automatically star that message in the chat
    //
    // TIP: You can inspect WhatsApp modules directly in your Chrome console by typing:
    // require("WAWebCmd") or any other module name. This will show you available methods,
    // _events, and other properties that might be helpful for this task.
