'I am trying to make a discord.js discord bot and I am getting the error: TypeError: interaction.isCommand is not a function

I am making a slash commands and keep getting the error TypeError: interaction.isCommand is not a function. I am using discord.js version 12.5.3. It says that it should work and I have seen a few videos using it.

bot.ws.on('INTERACTION_CREATE', async interaction => {

  if (!interaction.isCommand()) return;
  const commandName = interaction.Name
  const commad2 = interaction.name
  
  console.log(commandName + " " + commad2)

  if (commandName == 'name') {
    await interaction.reply({
      content: 'Yeet',
    })
  }
})

// Using the below I got it to say wow in console but nothing else and no error

bot.ws.on("INTERACTION_CREATE", interaction => {
  console.log("Wow")
  interaction.reply({ content: 'Pong!', ephemeral: true });
    if(!interaction.isCommand()) return;
    interaction.reply('Pong!')
})
