How to add IoTeX to MetaMask?

Can you guide me through the process of adding IoTeX to MetaMask? I'm relatively new to the world of cryptocurrencies and have been hearing a lot about IoTeX lately. I'm interested in exploring its potential but am unsure of the steps involved in integrating it with my MetaMask wallet. Could you please explain in simple terms how I can add IoTeX as a token on MetaMask and ensure that my transactions are secure? It would be greatly appreciated if you could also provide any additional tips or advice on managing my digital assets securely. Thank you for your assistance.
