How to add NTRn to MetaMask?

I'm curious to know the process of adding NTRn to MetaMask. Could you please explain, in a step-by-step manner, how one can accomplish this? I'm aware that MetaMask is a popular crypto wallet that allows users to store, send, and receive digital assets, but I'm not entirely sure how to add a specific token like NTRn. Would I need to have the token's contract address? Are there any additional steps I should be aware of? I'm hoping for a detailed yet concise explanation that would help me navigate this process smoothly.
