How to add Echelon Prime to MetaMask?

As a cryptocurrency enthusiast, I'm curious about the process of adding Echelon Prime to MetaMask. Could you please elaborate on the steps involved? I've heard that MetaMask is a popular wallet for managing and interacting with Ethereum-based tokens, but I'm not sure how to specifically add Echelon Prime. Would it involve copying a contract address? Or is there a more direct method through the MetaMask interface? I'd appreciate any insights you can provide on this matter. Thank you in advance for your assistance.
