How do I add Sui to Metamask?

Could you kindly explain the process of adding Sui to Metamask? I'm a bit unfamiliar with the steps involved. Could you guide me through the necessary actions, starting from accessing Metamask and navigating to the settings where I can add new tokens? Additionally, I'm curious about any specific details or requirements related to Sui that I should be aware of before proceeding. Your detailed instructions would be greatly appreciated.
